It has rare features like fabric upholstery and car phone.

After years of being under-appreciated, prices of the Porsche 944 are really starting to rise, particularly the later iterations. Apparently even Porsche Klassik knows that these front-engine models are increasingly admired because the division has a freshly restored example.

Porsche Klassik paid €18,500 ($21,544 at current exchange rates) for this 1991 944 S2. This was the ultimate naturally aspirated version of the model using a 3.0-liter inline-four-cylinder making 208 horsepower (155 kilowatts) and 207 pound-feet (280 Newton-meters).

This one had some rare features that made it particularly attractive to Porsche Klassik. First, where you usually find leather in these vehicles, this 944 S2 has fabric seats. A fantastic looking Blaupunkt stereo and separate equalizer dominate the lower section of the center stack. There's a car phone next to it. The M030 option gives the suspension Koni adjustable shocks at both ends.

The restoration here is more akin to what a normal buyer would do to make a good driver, rather than more comprehensive work to return it to factory fresh. There's a full repaint in the original Cobalt Blue Metallic, including taking the opportunity to replace the body's rubber seals when the doors and glass are off.

The interior received a thorough upgrade, too. The seat bolsters were looking a little rough, but Porsche Klassik sourced new-old stock fabric to recover them. With the cloth off, a technician also replaced the foam to make them feel like new.

Mechanically, this 944 S2 didn't need much. The biggest actual flaw was a non-functioning air conditioner that required a new compressor and a fresh charge of refrigerant. There were also the expected tweaks for buying a used car like an oil change and a new set of tyres.

With the purchase and restoration, Porsche Klassik says the total for this 944 S2 was €33,000 ($38,432 at current exchange rates). That's at the top end of the market. Looking at Bring a Trailer's completed sales, the most expensive S2 auction there was for a convertible that went for $37,997. The top coupe was $28,944.
