Sleeping giant: 1994 Audi Ur-S4 Monster for sale

There’s something in the water in Colorado. Or maybe it’s the altitude. Either way, we’ve seen some seriously badass Audis come from the Centennial State. This S4 looks like it could be just another mid-90s Audi, the visible FMIC and aftermarket wheels being the only tell-tale signs that this might be something special. Nothing alludes to just how special though. After a claimed $55k invested, it’s finishing its break-in period before the boost can be turned up to produce a Group B-esque 600hp from the 2.3L inline-5. I love that it’s not slammed, a stockish ride height maintained presumably for better charging of unpredictable mountain roads and conditions. Dirt, gravel, snow or tarmac will matter little to this beast though as it devours supercars all day long. If you’re ready to deal with a highly-tuned car but want to fly under the radar while carry the kids and some luggage, I can’t think of a better way to do it for under $20k.

Tuned 1994 Audi S4 for sale on eBay

An exhaustive list from the builder/seller:

Black on Black 1994 Audi S4, 118k. This car has got to be one of the very few nice ones left. It has a completely built motor, everything on it is essentially brand new (literally), all the goods you expect to find on a car of this caliber are there. Never in an accident, have traced the history of the car all the way back by talking with previous owners. Car currently has a 13psi tune on it for engine break-in purposes, approximately ~500 miles on the motor since being built, needs to have a final tune (that’s it) done to bring it up to its 600whp capability (proper break-in procedure was done on motor). I have a binder full of every receipt for every part put on the car, including all the final tolerances the motor was built to (engine build done by Ridge Reamer of Colorado). Car has a $55k agreed upon value insurance policy on it, based off of past 2 years of receipts spent on it, so if you don’t think it’s a good buy at $20k, then don’t bid on it, you won’t find another UrS like this…simple as that. I am happy to answer any questions or take additional photos upon request. This has been a west coast (rust-free) car that has been garaged its entire life (will provide previous owner’s detailed accountings of its past). Ebay’s AutoCheck says lists the car as a grey market car. The car was brought into the U.S. from Canada legally in 2008 and I have all documentation from Audi N. America that shows it conforms to U.S. DOT standards. Title is clear Colorado title.

*Car just got the clean bill of health from local Audi shop and compression was pulled on motor showing that it is breaking in perfectly.

The car’s AC system has been deleted to make room for the intercooler. Also the fuel cell does not have a fuel level sender unit in it, therefore the gas gauge on instrument cluster does not work. The Corbeau brackets do not slide back and forth either, they can be modified to have a slider installed again, but currently are fixed. Lastly, the entire steering column was swapped to an S6 steering column to make use of the factory S6 steering wheel and in the process some of the stalk controls do not work (i.e. windshield wiper lever is reversed and high beams don’t work), these features will be fixed before delivery of car is made.

I love this car. For the work done, the starting bid of $19,500 and described price as $20k seems reasonable. If you disagree, well, then these aren’t the droids you’re looking for. Spend a bit of time in the cockpit thanks to youtube though and it’s hard to say no to the sound of the classic Audi turbo’d five-cylinder spooling up and ripping away.
