OLD PORSCHES

964 Turbo

Most well-maintained Porsches of yesteryear are unlikely to lose value, and air-cooled 911s in particular have swelled in value as buyers seek an antidote to the more grownup, less charismatic watercooled models that arrived with the 996 generation in 1998. Indeed, prices for certain air-cooled examples have exploded of late: valuations for the last rear-wheel-drive 911 Turbos – the bellicose 3.3 and 3.6 964-series cars of the early 90s – can now top £200,000. It’s a market that’s been driven in part by speculators looking to cash in, and we’re now starting to see a trickledown effect on the traditionally less-loved front-engined Porsches that started with the 924.

One to watch: Porsche 968 (1992-1995). From £15,000

The most modern of the front-engined, rear-drive Porsche sports cars, the 3.0-litre, four-cylinder 968 succeeded the 944 and was available in coupé and convertible forms. The more focused Club Sport is the model of choice, but even a tidy standard car is a good bet.
