The A6 (C4 platform) is a great value,
when purchased used. Mine is a high
mileage car (127K) and it still runs
and looks like (almost) new. Keep in
mind that it needs some preventative
care (not just the regular oil change)
in order to keep it running flawlessly.
Timing belt (yes belt, not a chain like
most Beemers) need to be replaced every
60-75k. While doing this you should
also replace the water pump, because
it'll break down at some point, and
this will save you a lot of $$$$. Check
and top off the differential/tansaxle
fluids twice a year. Wear and tear
repairs done: Front wheel bearing,
front CV boot, timing belt and water
pump, differential seal.
The A6 has a smooth and quiet ride. It
looks great and the interior quality is
outstanding. It doesn't have the low
end torque like most American cars, but
it's good enough. The high end torque
(especially at Autobahn speeds 60-140
mph) is incredible. Good brakes.
Design engine with a maintenance free
timing chain, instead of a timing belt.
This may add a little bit of weight to
the car, but it'll save the owner
thousands of dollars in maintenance
costs during the life time of the car
