I'm looking at upgrading to a mid to late 90's vehicle; probably an A4 or A6 Quattro. Any advice from the list on specific things to check/watch out for or specific years/models that are particularly problematic would be most appreciated. Please reply off-list. Thanks in advance to everyone. Gary Meier 82 Coupe, 84 4KS, 86 Quantum GL5, 88 5KSQ, 91 Passat(about to be history)
