Porsche 911 Buyer's Guide

The 911 is the most liquid classic market in Britain, and our records show it working like one: 19 tracked sales from £12,430 to £110,000, median £40,612, with 88 lots live on the site as we write. The generations form a clean price ladder, which makes the buying decision unusually honest: you get the era you pay for.

Know your generations

Long-bonnet cars (1965–73). Three sales at £58,500, £100,000 and £110,000. The original short-wheelbase and early 2.0 to 2.4 cars are blue-chip collector stock; originality and matching numbers set the price, and restoration economics only work upward from solid cars.

G-series and 930 era (1974–89). Six sales from £37,662 to £103,500, median £46,046: impact-bumper Carreras, SCs and 3.2s, with Turbos at the top. The most usable air-cooled entry point, galvanised from 1976, and the volume of the classic 911 market.

993 (1994–98). One sale at £61,875, consistent with the last-air-cooled premium the wider market pays. Buy on service history and originality; the cars themselves are famously robust.

996 (1998–2005). Four sales, £12,430 to £56,250, median £14,994. The water-cooled entry point and the perennial value argument: the headlamps and the intermediate shaft bearing keep prices honest, and a car with the IMS invoice and no bore scoring is most of a 911 for a fifth of air-cooled money.

997 (2005–12). Four sales, £14,500 to £22,500, median £17,231. The consensus modern buy: 996 mechanicals matured, styling rehabilitated. Early 997.1 cars share the IMS consideration; 997.2 onward does not.

992 (2019–). One sale at £96,750; still a used car with a warranty mindset.

What to pay

Across our 19 sales: median £40,612. As a ladder: £12,000–£20,000 for 996 and early 997; £20,000–£35,000 for the best 997s; £38,000–£60,000 for G-series and SC/3.2 cars plus the 993 tier; £60,000 upward for long-bonnet cars, Turbos and the top air-cooled examples.

What goes wrong

Air-cooled: corrosion on pre-galvanising cars (kidney bowls, B-pillars, floors), top-end rebuilds on high-mileage engines, and originality checks that justify a specialist inspection at any price above £40,000. 996/997.1 and their era: IMS bearing (a documented fix), rear main seals, bore scoring on some engines; the invoices matter more than the mileage. Everything: verify the numbers match the certificate of authenticity; 911 values have long justified dishonesty.

Our view

For driving and keeping, the 997 is the pick of our data: £17,000 median for the car that fixed the 996's reputation, with parts and specialist support as good as the hobby offers. The brave save five figures buying a documented 996 instead and bank the difference against the known risks. Air-cooled money should follow condition, not year: a superb SC beats a tired 3.2 every time, and our £46,046 G-series median shows where the honest middle of that market sits.
