Not trying to put you off but every Audi I've ever driven has been so bland. They just don't seem to drive with any precision and the steering feels dead. I hope that performance Audis don't drive like that as I think you would be disappointed. They may be quick but are otherwise absolutely characterless. That's what makes the vr6 good; it has an engine full of character and drives with precision. Have you considered any other makes, maybe a Merc C43, BMW M3 or something by Porsche?
