I have had a mk1 tt and it was the most unreliable car I ever owned then I bought a merc slk and it was a great car. After 3 years of owning the slk a friend showed me the new tt that was coming out in a magazine and so I went to Audi and had a test drive.
I bought the 3.2 v6 brand new and it was a unreliable dog from the start. Electrical problems all over and Audi UK were less than helpful.
Avoid Audi as a company.
