The Bugatti Veyron of its day. Long, low, sleek with a great big six under its hood, the XK120 was the fastest car you could buy at the time, with an incredible top speed of 120 mph.
Just your average 1,001-hp, 8.0-liter, quad-turbo W16 powering an all-wheel-drive, two-seat, $1-million-plus hypercar. Top speed 253.52 mph. Or there's the 1,200-hp Super Sports at 267.85 mph.
