I know the car very well - as a good friend of the previous owner.
I bought my Sportback after driving his S3 from the same dealer and same sales person at Wearside Audi.
The car is a diamond mate you wont be disappointed.
The original owner was (still is) fanatical about his cars. It's had no expense spared and been detailed regularly.
We regularly have detail days around mine ;)
Sold mine now as ive just gone back into a company car and am just about to start a Golf Mk1 Project
and the previous owner of yours now has a TTRS ( as you'll probably already know).
A couple of photos of mine and his together.
& my old Sportback
Enjoy it mate :)
