I just looked at an 85 Coupe GT. I drove it, liked it, and might buy it. Its in very good condition with no rust, just runs a little rough. I'm wondering what are common problems with these cars. I'm coming from owning DSMs so I'm wondering what will be different with an Audi of this vintage. It is standard trans, 5 cyl, has ok power but I would do a tune up and a lot of little things to it. Thanks,

Robb
