I've never had Audi before, looking for an AWD wagon, I did take a 07' A4 2.0T with 35K miles for a test drive at Miller Audi in Parsipanny, NJ today.

Love the way it drives, but it definitely does not feel like a brand new.

I have few questions:
They can sell it either as a Cerified Pre-Owned, or without going thru that process, and no warranty for about $1200 less. Does the extra warranty worth it?
It would not cover regular maintenance.
How long-lived are the turbos on these engines? Any other parts, that may be problematic?

It's a NJ car, so where would I look for possible rusty spots?

If I buy it what would be the things to look at first?

How difficult would it be to add an iPod or other MP3/USB-connectivity to it? It has an in-dash CD changer.

Any experience with the Paul Mueller Audi in Parsippany, NJ service department?

Thanks a lot for your advice,
