Looking for a new DD and have come across a 96 A4 that has caught my eye. Im going to go check it out on sat and wondering if there is anything I should keep and eye out for since im new to Audi's. Here is the list of what I have been told it has done

1996 Audi A4

-164xxx Miles
-Leather
-2.8L V6
-5 Speed
-New valve cover gaskets
-New timing belt
-Tein S-tech lowering springs
-Custom LED headlights
-Flowmaster 40 series (Stock exhaust included)
-Custom APR tune (equivelent to stage 2)
-CD Player with new rear speakers
- New brakes
- Loaded options
-Custom europlate
-AC doesnt work but compressor does engage
-Passenger window doesnt go down but can hear the motor going so most likely just off track or broken pin

Any advice would be greatly appreciated
