Porsche 928

I purchased my second 928, a black on gray 1988 928 S4, in September of 2005. The car was extremely clean and stock, with less than 75,000 miles on it. I've done some mods, mostly the wheels, electronics and interior parts. It drives and sounds wonderful. The stero is fantastic and very stealth when the screen is not deployed. Having GPS satellite navigation in the car is very convenient and fits well with the forward-thinking design of the car. The suspension is well-suited to street driving, being smooth and compliant, though significantly more poised than stock.

Unfortunately, I must now sell the car with less than 78,000 miles on it, as I can no longer drive it. I'm asking $19,500 or best offer.

The factory-installed options on my S4 are:
C03 - California-type car
158 - Radio "Reno" (long gone)
494 - 2 speakers on back shelf
513 - Lumbar support - right seat
538 - Right seat with positrol and lumbar
570 - High output air conditioner
586 - Lumbar support - left seat
650 - Sunroof
While I had taken the GT on the track many times, I never wanted to track this car. It's be set-up for luxurious, sporty street driving. I drove the C4 Corvette on the track. My previous 928 was a rare monster, a 1990 928GT with dark rootwood interior, which now lurks somewhere in Oregon.
