i was actually about to buy a late 90s-ish audi a4, one of my favorite cars to date....
but i got a good deal on this MB instead
def pretty expensive to fix, but find a good reliable indie shop to do ur repairs, and take care of the car, and u should be in good shape.
make sure to get it checked out beforehand (extensively, might I add, since a car is a HUGE investment)
and enjoy the sweet ride, if you end up getting it. I
