Are Audi's good cars? I'm looking for a car and found a 1993 Audi Audi 90 GS...?

im considering buying it since its fully loaded and looks nice. The price is 1,300.... He asked for 1900 but I brought the price down...
Anyways, are these cars bad? Good? Expensive to work on?
How about parts?

Any Info is much Appreciated...
The milege on the car is 130,000...

THANKS!
