We soon be purchasing a friend's 1991 Model 80. It is a 5 cylinder, Automatic. Will have my garage check it out, of course but I always like to ask if there are any inherent problems with this model and year. Thanks in advance. -- "Audi, a great car, a great hobby" Len Ferrara - '87 CSTQ 5000 - 122,000 Son #1 - '82 Coupe - ???,??? Son #2 - '90 20V90Q - 72,000
