A tidy Porsche 911 can be had for the same money as a family hatchback - but if you're buying one here's some tips on what to look out for.
Our expert guide is Paul Stephens, an independent Porsche sales and servicing specialist based on Essex.
"The early 3.4-litre cars are more frail than the post-2001 3.6s," he says. "The engine's the problem. They develop cracked cylinder heads, dropepd cylinder liners and cracked intermediate driveshafts, all completely unpredictably.
"I've heard of scrapped engines at as little as 15,000 miles. And replacing an engine is a £10,000 job, unless you can find a crashed donor car. The only way to be sure you are buying a car with a good engine is to have it inspected."
Don’t buy a 3.4 before you’ve had it inspected. Rear main oil seal and intermediate shaft seal also have a limited life; those are £540, every couple of years. Air mass meters and ignition coils are troublemakers, too.
