28. 1995 Ferrari F50
Just 349 of these beauties ever rolled off the assembly line. Powered by a 4.7 L Tipo F130B 60-valve V12 engine, this six-speed manual generated a ridiculous 512 horsepower. Suffice it to say, it was a gas guzzler, getting a combined 8 miles per US gallon (7 city, 10 highway), although when you’re driving a machine that can go from 0-60 in 3.8 seconds and 0-100 in 8.5 seconds, are you really worried so much about the cost of gas?
