The seller leaves a bit of UR-Quattro history in his ad, so I'll skip that.
This car has just 16,069 miles on it. The seller bought it last year with the intention of turning it into a "400 plus hp monster". Fortunately, after realizing how nice the car is, he scrapped that idea.
This may be the same car I wrote about last year, but have no way of knowing.
