I've owned like 28 different cars, but many were similar models
Ford (several of these) 1969 Mustang, 1961 Falcon, 1975 Courier (mazda b1600 elsewhere)
Chevy (several of these)
GMC (Chevy's higher optioned, only a few chrome bits and electronic extras)
Merkur (The XR4ti in the U.S. was released under a new brand, like Scion to Toyota)
Mitsubishi (a Lancer OZ edition and a 3.0L Eclipse GT)
Subaru (not counting part-cars, my 7th coming soon)
I still would like to add:
an older Rolls Royce
at least one lotus
something Nissan - GTR 33 or 32
