So, my wife has decided that she "needs" an A4 Cabrio.
Trying to decide which one to look for... my main concern is reliability. (I'm a VW owner, so I know that repairs can be painfully expensive).

We've pretty much decided that Quattro is what we want, but are undecided on power train options (1.8, V6, auto, manual). Performance and mileage aren't terribly important... she doesn't pile on too many miles and we already have a sports car for when we want to go fast.

Any thoughts on which one(s) (assuming they've been cared for) are likely to be the most reliable?

TIA for any words of wisdom.
