8. Porsche 911 Turbo S Convertible: $2,674
Oh, the timeless Porsche 911 Turbo S. One of the most historic cars, and with a 530 horsepower, six-cylinder in the back, also one of the quickest. We just hope you can afford the insurance. Although, if you can stomach the $172,000 price tag, you can probably make the insurance payments too.
