If I were a rich car collector that wanted a variety of cars to drive when the feeling struck, Id have a couple dozen cars, one of them would be one of these

but with at least 200 horsepower so it could merge into traffic. I heard these are really underpowered

FWIW, I'd have this list of cars in that imaginary collection:

Messerschmitt Tiger, Isetta 300, 69 Corvette 427 tri power 4 speed, Hurst Super Stock Dart, 69 George Hurst Olds prototype, '32 roadster, land speed racing Bellytanker, '68 429 Boss Mustang, 65 R code GT 350, '65 427 side oiler Cobra, Golden Sabre GTO, that Penske Sunoco Camaro, the McQueen Baja Boot, and Thomas Crown Affair Meyers Manx, the Smokey Yunick Hurst Floor Shift Special, a hemi GTX, a Buick GNX, a 60s mini, a great old Morgan

well, that's a good start to a list
