The eighties sports cars had charm.... Even the little fox body mustang had some. I just helped if you didn't mind edges, or boxes.
I loved the datsuns from the early to mid 70's. The old toyota coupes from the early 70s looked like pocket sized muscle cars. Old J-tin is pretty cool. Then in the eighties you had the audi qauttro coupe, the e30 bmws, the ae86 corrola, aw11 mr2, the fc3s RX-7, the porsche 944, the delorean, the countach.... the list goes on and on. Modified versions of any of those can really knock your socks off visually.
Once I even saw a fastback Fiero GT that was nice looking although that was probably mere coincidence.
