The early years · 1973-1977The historical price trends of the early G-Series cars and their variants: trends, investment potential and forecasts to 2030. For the June 2026 update the series has been rebuilt on the Classic Data market values (via Zwischengas) and supplemented by 161 documented sales from the MarqueScope SOLD archive.
This analysis examines the historical price trends of the early Porsche 911 G-Series (1973-1977) and its various model variants. Drawing on extensive data, it identifies trends, sets out where the investment potential lies and offers forecasts to 2030. The material should be of value to collectors and investors alike who take an interest in this iconic sports car.
For the June 2026 update the historical series has been rebuilt on the Classic Data market values (condition grade 2, retrieved via Zwischengas, as at May 2026) and supplemented by 161 documented sales of early G-Series cars from the MarqueScope SOLD archive (October 2025 to June 2026, de-duplicated, repeat listings of the same car counted as one sale each). The tables marked as at 2025 still give the average prices from the earlier 911Finder analysis, while the 2026 figures are median sale prices; this change of method is flagged in every table and chart.

Since the June 2026 update the curves are based on the Classic Data market values for condition grade 2 (very good, fault-free), retrieved via Zwischengas (as at May 2026). They show a volatile picture: after a flat spell from 2011 to 2013 came the steep climb of 2014 to mid-2016. It was most pronounced on the Carrera 2.7, whose Coupé rose at grade 2 from €86,000 (mid-2014) to a peak of €225,000 ; that figure stood unchanged in the tables from June 2016 to November 2017. A stepwise correction followed to mid-2020 (Carrera 2.7 Coupé: €140,000), then a flat spell in 2020/21 and a recovery in 2022/23 in which the base models and the Carrera 3.0 even reached new highs. Finally, between the January 2026 and May 2026 tables, Classic Data cut all ten series by roughly 10 per cent.
Market values for cars at condition grade 2 (very good, fault-free) from the Classic Data price tables, retrieved via Zwischengas (as at May 2026). One data point is given per year, at mid-year (2011: October, 2025: July, 2026: May). "Peak" means the highest annual data point in the series since October 2011. The Classic Data series 911 Carrera (1973-1975) corresponds to the Carrera 2.7.

Source: Classic Data market values (condition grade 2) from the tabulated price series, retrieved via Zwischengas, as at May 2026; annual data points selected by 911Finder. The Carrera series stood at their boom highs unchanged in the tables from June 2016 to November 2017, before Classic Data cut them by roughly 19 to 20 per cent with the February 2018 tables. For the Carrera 3.0 Coupé the grade-2 peak of €75,000 stands in the tables from August 2023 to January 2025 (annual data point for May 2023: €74,800). The reduction of roughly 10 per cent between the January 2026 and May 2026 tables applies to all ten series.
Setting the June 2026 median sale prices in context: the medians of documented sales sit above the grade-2 market values and mostly close to grade 1. The Carrera 2.7 Coupé achieved a median of €195,000 , more than the Classic Data grade-1 value of €184,000 (May 2026). At €99,000 the Carrera 3.0 Coupé sits between grade 2 (€65,500) and grade 1 (€104,000), as does the 911 S Coupé at €67,500 (grade 2: €47,300, grade 1: €71,800) and the base catch-all Coupé cell at €69,700 (grade 1: €67,100 for 1973-1975 and €71,500 for 1975-1977). None of this contradicts the May 2026 reduction in market values: the SOLD archive is dominated by prepared, ready-to-sell dealer cars whose final prices sit at the top of the condition scale. The Carrera US (median €114,950) has no Classic Data series of its own and trades well below the Carrera 2.7 series of the German market.
| Model | Average price (as at 2025) |
|---|---|
| Porsche 911 Carrera 2.7 (1974-1976) | approx. €110,000 (Coupé), approx. €95,000-100,000 (Targa) |

161 documented sales of early G-Series cars (1973-1977) from the MarqueScope SOLD archive (October 2025 to June 2026). The full export comprises 1,045 SOLD records from the G-Series family, with no URL duplicates; 175 records without a price and 5 below €15,000 were excluded, leaving 865 analysed. Cells follow the platform’s model label, and catch-all cells with no variant given were assigned to 1973-1977 by their year of first registration. That gives 165 sale records for the early G-Series cars; seven of those are repeat listings of three cars and were counted as one sale each. Prices are the last recorded asking price of the car that sold.
| Model | First registration range | Sales | Median | Range | Median km | Days on market |
|---|---|---|---|---|---|---|
| 911 (base, catch-all Coupé cell) | 1973-1977 | 20 | €69,700 | €39,950 - €116,911 | 97,834 | 30 days |
| 911 Targa (base, catch-all cell) | 1974-1977 | 15 | €69,900 | €43,900 - €119,911 | 109,000 | 37 days |
| 911 S | 1974-1977 | 29 | €67,500 | €39,900 - €150,000 | 108,700 | 77 days |
| 911 S Targa | 1974-1977 | 19 | €64,995 | €26,911 - €174,999 | 145,967 | 57 days |
| 911 Carrera 2.7 | 1973-1976 | 25 | €195,000 | €68,000 - €350,000 | 53,566 | 147 days |
| 911 Carrera 2.7 Targa | 1973-1975 | 10 | €171,940 | €109,900 - €210,000 | 84,236 | 148 days |
| 911 Carrera 3.0 | 1975-1977 | 21 | €99,000 | €73,000 - €189,930 | 97,495 | 75 days |
| 911 Carrera 3.0 Targa | 1976-1978 | 7 | €79,900 | €74,911 - €89,911 | 139,338 | 149 days |
| 911 Carrera US | 1973-1975 | 9 | €114,950 | €63,700 - €129,900 | 88,550 | 58 days |
| 911 Carrera RSR 3.0 (competition special) | 1974-1975 | 3 | €1,152,020 | €1,062,744 - €2,657,700 | 23,281 | 55 days |
Cells with fewer than 3 sales are not shown as rows of their own: one 911 Carrera US Targa (€143,678) and two cars recorded as a "Carrera 3.0 Cabriolet" (€79,500 and €92,000, first registered 1977). The latter are a platform recording error: there was no factory Cabriolet before 1982, and both listing URLs describe the cars as Targas. One car listed as a "Carrera RS" (first registered 1973) had no price and was not analysed. On the plausibility of registration dates: individual Carrera 2.7 and Carrera US cars first registered in 1973 are early registrations of the 1974 model year (production began in autumn 1973); a Carrera 3.0 Targa first registered in 1978 is a late registration after production ended in summer 1977. As a competition special, the Carrera RSR 3.0 row (n=3) carries only limited weight and does not feed into the production-car analysis. Days on market = the median listing duration in days, rounded. Repeat listings of the same car, recognisable by an identical first registration and mileage at the same or almost the same price, sometimes across several sources, were counted as one sale each, taking the last recorded price. That applies to a Carrera 2.7 Coupé listed twice (€350,000), a Carrera 3.0 Coupé listed three times (last at €189,930) and a Carrera 3.0 Targa that is also the €92,000 "Cabriolet" record mentioned above and is counted there only. With 7 sales, the Carrera 3.0 Targa cell now carries only limited weight.
A detailed analysis of how prices for the early Porsche 911 G-Series have moved reveals several notable trends.
At an average of roughly €110,000 (Coupé) and €95,000-100,000 (Targa) in the series as at 2025, the Carrera 2.7 remains the most valuable early G-Series car. As the direct successor to the legendary Carrera RS it keeps its special place in the market. It is worth noting, though, that its Classic Data market value at grade 2 in May 2026 sits roughly 41 per cent below the peak of 2016/17 (Coupé: €132,000, down from €225,000), which underlines how volatile it is as an investment.
The June 2026 sales data underlines that special position: a €195,000 median for the Coupé (25 sales) and €171,940 for the Targa (10 sales), on the low mileages typical of collector cars and with spells on the market of almost five months. The gap to the 2025 averages reflects not only the market but also the change of method to a median sale price and the high-quality mix of cars on offer.
At roughly €55,000-60,000 in the series as at 2025, the Carrera 3.0 shows steadier value than the Carrera 2.7, albeit at a lower level. The smaller swings may appeal to more risk-averse investors: its Classic Data peak comes not from the boom but from 2023/24 (Coupé, grade 2: €75,000), and the May 2026 table still shows €65,500. In June 2026 Carrera 3.0s that sold achieved a median of €99,000 (Coupé, 21 sales) and €79,900 (Targa, 7 sales, a small cell).
At averages between €35,000 and €40,000 (as at 2025), these cars are the cheapest way into the early G-Series. Their relative price stability after the initial rise is a point in their favour. For enthusiasts who also want to enjoy driving, they offer excellent value. The June 2026 median sale prices are tightly clustered between €64,995 and €69,900 across all four cells (base and S, each as Coupé and Targa).
| Budget | Recommended | Reasoning |
|---|---|---|
| up to €70,000 | 911 base model or 911 S (Coupé/Targa) | The largest supply in the archive, median sale prices of €64,995-69,900; an authentic way into the early G-Series world |
| €70,000-€90,000 | 911 Carrera 3.0 Targa | Median sale price €79,900 (a small cell of 7 sales); the torquey 3.0-litre with an open body |
| €90,000-€120,000 | 911 Carrera 3.0 Coupé or 911 Carrera US | Median sale prices of €99,000 and €114,950; rarer than the later 911 SC, and a sought-after basis for a collection |
| €120,000-€180,000 | 911 Carrera 2.7 Targa | Median sale price €171,940; the open-top way into the Carrera world, with the 210 PS engine |
| over €180,000 | 911 Carrera 2.7 Coupé | Median sale price €195,000; the direct successor to the Carrera RS and the pinnacle of the early G-Series |
The budget bands are derived from the median sale prices in the MarqueScope SOLD archive (Oct. 2025 to June 2026). Individual cars can sit well below or above them depending on condition, history and specification.
Detailed expert knowledge on the Porsche 911 G-Series (1973-1977): market data, model variants, criteria for originality, value-adding features and price forecasts.
Given how prices have actually moved since 2011, and above all the consolidation after the boom of 2014 to mid-2016, the forecast to 2030 has to be framed more realistically.
The market as a whole: The market has already been through a correction, which points to a degree of maturity. The extreme rate of appreciation seen from 2014 to 2016 is very unlikely to repeat. Average annual appreciation of 2-4% looks more realistic for high-quality, original cars.
| Model | Current value in 2025 | 2030 forecast (moderate) | 2030 forecast (optimistic) |
|---|---|---|---|
| 911 Carrera 2.7 Coupé | €110,000 | €120,000-€130,000 | €140,000-€150,000 |
| 911 Carrera 2.7 Targa | €95,000-€100,000 | €105,000-€115,000 | €120,000-€130,000 |
| 911 Carrera 3.0 | €55,000-€60,000 | €65,000-€75,000 | €80,000-€90,000 |
| 911 S | €40,000 | €45,000-€50,000 | €55,000-€60,000 |
| 911 base model | €35,000-€40,000 | €40,000-€45,000 | €50,000-€55,000 |
The forecast is based on the average prices in the series as at 2025 and is deliberately not mixed with the June 2026 median sale prices; those rest on a different method (the median of documented sales rather than an average price) and are shown separately above.
Younger collectors entering the market could shift demand for the early G-Series cars, though that generation’s preferences may lean more towards newer models.
Growing electrification in the new-car market could steady interest in classic combustion-engined cars, though whether that translates into significant price rises is unclear.
Possible restrictions on combustion-engined cars in city centres could affect the market, though exemptions for historic vehicles are to be expected.
Interest rates, inflation and the wider economy will continue to shape the market for collector cars.
The early Porsche 911 G-Series (1973-1977) has established itself as an important milestone in the development of the 911. The market data shows, though, that values do not rise as linearly or as steadily as is often assumed. A phase of spectacular price rises (2014 to mid-2016) was followed by a clear correction, particularly on the expensive Carrera 2.7; most recently Classic Data cut its market values again by roughly 10 per cent in the May 2026 tables.
The market for early G-Series cars now shows growing discrimination and maturity. Authenticity, originality and condition are the decisive drivers of value. The once enormous price rises have slowed markedly, which points to a more realistic valuation of these cars.
For investors the segment offers moderate prospects, with likely annual returns of 2-4%, still above the average rate of inflation. The volatility of prices, particularly on the expensive cars, nonetheless calls for caution over short-term strategies.
Enthusiasts who put driving enjoyment first can share in the myth of the early Porsche era at comparatively modest entry prices, with the base models or the 911 S. These offer an authentic driving experience together with greater price stability than the expensive Carrera 2.7.
Financial considerations aside, the early G-Series cars remain timeless design icons and demanding sports cars to drive, offering an incomparable link between historical heritage and dynamic experience. They represent an era of car-making in which technical refinement, aesthetic elegance and a purist driving experience came together perfectly: qualities that will secure their place as sought-after collectors’ items in the future too.
The data used in this analysis is based on market observation, sales statistics and expert assessment from a range of sources. The sales data from June 2026 that is marked as such comes from the MarqueScope SOLD archive (October 2025 to June 2026, de-duplicated, repeat listings merged, marquescope.de). All other prices are averages and can vary considerably depending on a car’s specification, condition and mileage.
