Ford stylists cleaned up the Mustang GT for '83 with a leaner profile and slippery lines. These were great fun to drive and remain so today, especially if you can find a T-top version. Mid-year, Ford offered a five-speed manual transmission. If you're looking for something unusual, check out the Mustang GT Turbo with a 2.3L OHC turbocharged four. These cars make terrific conversation pieces from the short-lived turbo era.
