Optioned to Turbo S spec, it must be one of the best examples around.

Just a couple of years ago, the best 993-generation Porsche 911 Turbo in the entire world would barely have been worth six figures. But one has just come onto the market at a British dealer bearing the hefty price tag of £199,995 ($243,747).

It is, at least, an immaculate example, fitted with the desirable X50 option package, which effectively turned a mere Turbo into the searing Turbo S. The pack included the engine management system, oil cooler and dual exhausts from the Turbo S, thus matching that car’s output of 430 horsepower (331 kilowatts). The pack added the Turbo S badge and its yellow brake calipers, as well.

The original owner also specced the X79 pack, which added air inlets to the rear wing and Turbo S front air intakes.

The 993 Turbo was an absolute sensation when it launched in 1995. Even by modern standards, it’s a fast car. Like, really fast. In its July 1997 test of the full-blown Turbo S, Car and Driver clocked a 0 to 60 miles per hour time of just 3.7 seconds, and a top speed of 188 mph (303 kilometers per hour). Thanks to standard-fit four-wheel-drive, it was probably the fastest point-to-point car in the world at the time, too.

This one was first to delivered to Japan in 1995 - one of only 60 left-hand-drive X50 cars to be sold there - and is now registered in the UK. Finished in gleaming Grand Prix White, it shows just 26,200 miles (42,200 km), backed up by a full service history.

The interior features electric sports seats with body-color backs and yellow seatbelts, air-conditioning, twin airbags, and full black leather upholstery.

You might think that spending 25 per cent more than the cost of a brand-new 911 Turbo S on its 20-year old predecessor which, in every measurable way, isn't as good, is a crazy idea. But as prices of late, air-cooled 911s have reached the stratosphere, this one actually looks quite good value.
