Car and Driver , September 2007


The Thunder Ranch 550 Spyder can be devilish. Above 80 mph, wind turbulence delivers rabbit punches, and some sort of eye protection is a must. The transmission in our car had a short-shift kit that made the four-speed’s throws annoyingly stiff. Stops from 70 mph required a lengthy 224 feet, so braking demands advanced panning. Focusing on the numbers misses the point, however, as this is not a numbers car. It’s plenty quick – 5.5 seconds to 60 mph – but more important, it has a vintage feel.
