I have heard of many occasions when a piece of garage jewelry has been driven properly for the first time and resulted in spectacular engine failure. My mate Steve that was on the Rockingham day in the blue S1 bought his '97 S1 with 20, 000 on the clock and put a con rod shaped hole in the side of the block on the way home.
Not mention that if will probably need a suspension refresh and new tyres if still on the originals.
