Tuner Tuesday: Porsche 968 Cabriolet Supercharged

I’ve always been somewhat intrigued by the Porsche 968 Cabriolet. Before SUVs and sedans graced Porsche’s lineup, this was a bit of an outlier, a car more suited for cruising than its hardtop sibling, yet packing the same potent large displacement inline-4 under the hood. Someone decided to turn this formula up to 11 with this example we see here for sale in California. This 968 Cabriolet packs a supercharger, with an output of over 300 horsepower. Mated to the preferred 6-speed manual gearbox, this can make for some seriously fun al fresco motoring.

All 968 cabs are special, but this one is particularly rare, with rare factory options and special and tasteful upgrades and modifications.

It is a 1992 the first model year ever made, (production date 12/1991), with exceptionally low miles for a 24 year old car.

It is one of only seven 968s cabs ever produced to have Full Factory Leather option in Cashmere tan (out of a total production of over 2000 cabs brought to North America).

The door panels, the door handles, the seat backs, the center tunnel, lower dash, armrest, etc. are all in gorgeous Cashmere Tan leather. You may not see another one outfitted like this for sale. This was a $4000+ option from the Porsche Factory back in 1992.

I am not a car dealer. I’m just a 968 enthusiast. This car was bought by me in April of 2014 at a local dealer. I have METICULOUSLY gone through the entire car over the last 2 years to bring it to perfect running order, and more, installed many appropriate upgrades and modifications.

I have been asked is the car will pass Smog test with the supercharger system and the answer is YES, ABSOLUTELY. This is a CARB approved and certified system — and the car as the sticker from Cali to prove it. And it passed smog test a few months ago. Message me, and I will send you a pic of the CARB seal and the smog test — I am maxed out at 24 pictures, otherwise I would post them directly to eBay. Thanks.

Like it’s other front-engined sibling, the 928, 968 prices have been on the rise. We’ve seen good examples of 968 Cabriolets reach well into the $20,000 range. A modified car, even one with low mileage, will tend to affect the value to an extent. The installation of the supercharger and other performance bits on this 968 look to be done to a high standard and even the newer Cayman alloy wheels look at home in this application, a testament to how forward thinking this design was over 20 years ago.
