More detail:

Unfortunately, the time has come to sell my 1993 Audi S4 (UrS4). I have owned this car for over 10 years and it has been a fantastic vehicle without a single issue the entire tenure of ownership. I am the second owner and babied this car just as much as the first owner. Garaged 99% of its life and pampered, this example still smells and feels new (seriously amazing leather smell). I hate selling, but I have a shoulder injury that will no longer allow me to drive a manual transmission. My plan was to keep this forever, so I have taken care of any and all maintence for some time. It has been smogged and checked out recently in SF and passed with flying colors. This engine is in tip-top shape.


Not a speck of rust on the body of this example. The pearl paint is in fantastic, and gets a lot of compliments. There is a tiny bit of cracking on the clear coat on the trunk, I think this can be buffed out with a clear coat etch. You can not even see the cracks unless you are VERY close.


The interior is pristine. The carbon fiber trim does not have a single crack and looks amazing. Also, like I said before the leather still smells new. I regularly (~every 6 months) condition the leather with griot's leather rejuvenator and clean every square inch. The bolsters of the recaro seats tend to wear out, but they look great on this car and are still soft to the touch.

The interior of UrS platform is top notch, from the recaro seats to small details like gauges with white faces and the UrS “S” logo - they simple do not make interiors like this anymore.


The 20v Turbo just sings, this is one of the finer examples of this amazing motor configuration. The turbo has absolutely zero play. The engine will not consume a single drop of oil (or any other fluid) between every 5K oil change (always with Rotella T6). Pulls very hard (and fast) to redline. The 034 tune is very linear boost and feels great - overboosts to 22lbs and will taper slightly to redline, and pulls like a freight train.

Travel - out of California

I live close to SFO airport - so if you would live to fly out and drive home I am happy to swing by and pick you up. I would trust driving this UrS anywhere in the country. Let me know if you need this type of accommodation.
