Widened Wagon: 2001 Audi S4 Avant RS4-spec

After a string of quick Mercedes-Benz wagons, it’s time to take a look at the maker most associated with bonkers 5-doors. While Audi may have never imported any of their fastest wagons into the United States, since the 5000CS quattro Avant the maker has been intrinsically linked with speedy family rides. While we got some good ones in the former, the 200 20V quattro, and the C4 and C5 S6 Avants, the real speed was always in the “RS” line. With the exception of the S6 Plus, all of the top-tier models have carried the RS moniker and traditionally have been the engine blueprint many Audi fans have followed to get the best speed. If they’re really devoted, they take it to the next level and copy the look as well. The result can be very impressive, as shown in this RS4-spec 2001 S4 Avant:

To me there are two way to look at this car. A labor of love, it’s asking price is only a fraction of the price invested and – notably – significantly less than real RS4s that are still not legal for import. A few have been federalized, but asking prices range from double to quadruple the asking price of this example. The other way to look at this is that it’s a very expensive S4 Avant that’s been heavily modified and personalized. I would have done things differently, but I applaud the builder for seeing this one through tastefully. If you like the look and it was done correctly, it’s a tremendous amount of performance and work for a budget price.
