speed 3 is more of a raw sport compact, whereas the speed6 is more luxury meets sport. it really just depends on what you are looking for in a car.I am also looking at a speed 6 , I keep reading that some people have gotten their engines and turbo seals replaced. I was just wandering is this a very common thing, or just a rare occasion. I am also looking at a speed 3, is this a better choice?
