1993 Audi S4

It hasn’t been too long since we looked at a C4 Audi, but 30 years on they’re now so rare to find in decent shape that it’s quite notable when you do see one. Today’s car is far from stock, like the last one – actually, even moreso. Turned up in essentially every way, it’s a built monster that’s ready to rock. Despite that, if you like the work that’s been done these are still remarkable performance deals.

I am listing my Audi S4 for sale. I purchased the vehicle May 2021. I have been working on it and sourcing parts for it since then. I believe he was the 2nd owner and owned it for over 20 years! I wanted to find a nice southern car with no rust and this was the one. I did not worry about miles too much as long as the car had no salt / corrosion damage. My plan was to build the car fully and to do it at sections at a time. At this point I have a LOT into the car and countless hours of labor and finding parts that are no longer available. All of the parts I bought new. All of the parts have less then 5k miles on them. I believe that the valve stem seals are starting to leak slowly. I get a little smoke on start up then it goes away once the vehicle has warmed up. Very little oil consumption. A/C Blows Ice cold.

Here is a list of what I have replaced so far in my possession. Everything was new and if used it was specified.

This really has all the go-fast stuff on it, and while I’m not a fan of the wrap that could be changed. I’d guess the paint underneath is shot, though. Still, that’s not where the value lies here – this car easily has twice the asking price worth of modifications and work performed. For about the same price as a tired E36 M3, you’ve likely got the best part of double the horsepower and a much more luxurious package that is also far more rare. If you like Audis and can confirm that the work performed was done right, this one looks like a solid deal.

    Maybe I am blind, but isn’t that an S6?

    C4 1992, 1993 and 1994 UR S-models were called S4, the later ones S6.

    Audi had a bit of an identity crisis during this period and then changed the nomenclature of their line up. I personally miss the days when Audi’s offerings were only A4, A6, A8 then their S/RS counterparts. Simpler times with better designs. B5 RS4, C5 RS6, D2 S8 are some of the most iconic vehicles offered from that Marque in addition to the UrQ and RS2 from the previous era.

    Usually I don’t like the heavily modd’ed cars, but this one looks pretty good. Agree the wrap is a bit of a bummer, but if you could get this for 15kbthats a lot of car for the money!
