The Mustangs are crude by modern standards, but strong engines and low prices keep them desirable next to the more refined sport coupes and convertibles on the market for a long time. The performance-oriented Mach 1 is has awesome power, handling and retro design, while the GT offers V8 power for under $25,000. Even V6 models can be entertaining when equipped with a manual transmission. Both the GT and the V6 make fine daily drivers, especially for those who crave tail-out thrills and don't mind a less-than-ideal seating position.
