I'm seriously looking at upgrading from my old A4 to an A6, ideally Avant. Is there a particular version you would recommend to me, or one that you would avoid.

My wish list is:

Avant, but would go with saloon

leather interior, really want leather

ideally manual

petrol or diesel

2ltr (ish) not interested in Quattro

year 2001 upwards

high mileage (130k max) if the service history is in place

As many gadgets as possible

6-7k is the budget

Are my expectations reasonable?
