Go for the Lexus mate, all those extras and lot more exciting looking interior. I haven't any friends with an A4 but have with A3's and TT's. They've both had a fair bit of trouble, window clips breaking, excessive tyre wear and unhelpful dealers. Saying that a mate of mine has a Golf V6 2.8 4motion and he's had an even more terrible time! All these cars share parts and stuff and they just dont seem to be that reliable. Also the VW warranty is getting smaller and smaller, not sure if this applies to Audi as well or not?
