Porsche 996 Turbo & Turbo S Price Development

After the steep initial fall in value between 2000 and 2010, prices reached their low point between 2010 and 2015. Since 2015 a continuous rise in value has been visible.

Unlike the standard Carrera models, the Turbo variants reached their low point earlier and have risen continuously in value since 2015.

The Turbo S cars, with their considerably smaller production numbers (600 Coupés, 963 cabriolets), show better value development than the regular Turbo versions.

Looked at historically, the cabriolet sat at a slightly higher price level than the Coupé on both variants. The sales data from June 2026 draw a different picture: on the Turbo (€84,900 against €77,990) and on the Turbo S (€111,999 against €101,850) alike, Coupés most recently traded above the cabriolets. On the Turbo S this fits the production numbers, because at 600 cars the Coupé is the rarer one (cabriolet: 963).

The Mezger engine fitted to the Turbo is regarded as extremely robust and undemanding, which helps it hold its value in the long term, because the known problems of the standard engine (IMS failure) do not occur here.

• The manual premium is the key figure of this update: Turbo Coupés with a manual gearbox achieved a median of €84,900 (200 sales), Tiptronic cars €72,900 (129 sales), a gap of €12,000. On the cabriolet the effect is small (€79,800 against €77,626); on the Turbo S variants the manual cells, with 4 and 2 sales, are too thin for reliable statements
• The market has overtaken the 2025 forecast: the Coupé median of €84,900 is above the forecast value for 2027 (€72,000) and practically at the 2030 level (€85,000); at €111,999, the Turbo S Coupé likewise already exceeds its 2027 mark (€105,000)
• The Coupé beats the cabriolet, against the previous order: 996 Turbo Coupé €84,900 against €77,990 (cabriolet), Turbo S Coupé €111,999 against €101,850 (Turbo S cabriolet). On the Turbo S this fits the numbers, because at 600 cars the Coupé is rarer than the cabriolet (963)
• Mileage as a driver of value: the Turbo S cabriolet shows a median mileage of 51,605 km, low in the way collector cars are, and the most expensive sale in the archive is a Turbo S cabriolet at €216,652 with 27,909 km
• The factory power enhancement (X50/WLS): explicitly documented as fitted on only 6 of the 417 sales, too few for a reliable statement about a premium
• Time on the market: a median of 28 days for the cabriolet, 38 for the Turbo S Coupé and 42 for the Turbo S cabriolet; for the Turbo Coupé the figure is not reliable because of the platform artefact declared above (the 0-day entries)

Complete documentation of all servicing is essential. Because of the high output, many 996 Turbos were used hard, so regular oil changes (ideally every 10,000 km) are particularly important.

The epoxy joints of the turbo coolant lines can fail over time and lead to a massive loss of coolant. A check and, if needed, preventive replacement are advisable.

On manual cars, listen for shifts free of crunching, particularly from first to second. That points to synchromesh that has been treated well.

If a car has the ceramic brakes (optional on the Turbo, standard on the Turbo S), their condition should be checked carefully. A replacement can quickly swallow a five-figure sum.

On cars said to have the X50 factory power enhancement, always check for the corresponding code on the sticker in the front luggage compartment. Tuning carried out later should be viewed with scepticism.

While the Tiptronic is regarded as the more robust, cars with a manual gearbox generally achieve higher prices thanks to their sportier character and have better potential for growth in value.

Watch for signs of accident damage. The complex all-wheel-drive system and the wider body make repairs to a 996 Turbo considerably more expensive than on the standard cars.

The moderate to strong growth in value of recent years will probably continue, and the rarity of the Turbo S should lead to disproportionate development.

As a technical jewel, the Mezger engine will be valued as a special feature as it grows older, much as air cooling is on older 911s today.

A new generation of buyers who grew up with the 996 is now entering the stage of life in which they can afford one, which should increase demand.

Immaculately kept cars with low mileage will rise disproportionately, while high-mileage cars will gain in value more slowly.

Porsche's support for its classics and the good supply of spare parts will help these cars survive in the long term and so support their appeal as collector's cars.
