Recently at sweltering Goodwood, I got a hill climb ride in the 700-hp Praga Bohema with original Stig Ben Collins—who helped develop it. Climbing onto the carbon-fiber side pod to squeeze into the low-slung seat (3.9-inch front ride height, 2200 lbs total weight) left me sweating, but the thrill took over fast. Only 89 of these Czech supercars exist, and it even needs a three-point turn (limited steering lock) to line up. That launch? My stomach dropped like a roller coaster—obsessive weight cuts (no active aerodynamics to save 55 lbs) made total sense. Ever had a heart-racing car ride? Or a rare supercar you’d love to ride shotgun in? Comment below!
