The 1995 is not OBDII and is not quattro. I bought a 1996 A6 Quattro for $3,000 and it still is not yet driveable after one and a half years. It now has a coolant leak and makes a grinding noise when accelerating.I have the Audi shop manual CD from
www.bentleypublishers.com. The ones you are looking at are nearly all worn out,with higher mileage thanmine, so you would be buying a carwith defered maintenance and emission problems. Audi parts and tools are very expensive. Audi requires special oil, ATF, coolant, premium gas,etc., so it gets even more expensive. Few repair shops have the proper Audi tools.
So, a worn outAudi is a money sink hole, even if youdoyour own repairsand spend$2,000 on parts and tools.Do you have a reliable spare car, while yourepair your Audi?
Don't buy any high mileage car with transmission, engine troubleor other costly repairs such asthe timing belt, water pump, brakes, tires, etc. Always test drive a car for transmission, engine problems, and cv joints. Watch the exhaust pipe with the engine running for smoke or water.
Repairing your Honda with only 220,000 milescould also becostly, but is possible. If you are unable to repair an old honda, then how willyou be able to take on a worn outAudi which requires the ATF change every 45,000 miles, but was never done?
You shouldbe able to find a 1998 A6 Quattro or 1998 A6 Quattro wagonin good condition for around $7,000 with about 100,000 miles or less. However, there is always the problem of defered maintenance. So beware, that most used cars will need an ATF change, timing belts, head gaskets, emission parts,etc.
