The BMW M Roadster is a car that people will either love or hate. It's that simple. I personally think that it's one of BMW's finest cars, complete with great looks and performance to match. Powered by a 315 horsepower inline-6 engine, the M Roadster can reach speeds as high as 155 miles per hour and can accelerate from 0-60 mph in just 4.8 seconds. The car is also one of the best looking BMWs available, and has a unique style similar to that of the Z3 with a few minor upgrades. Bring on your Boxster!
