I found a good deal on a 2007 Mazda Speed6. I think just the sport model. 44K miles, a lot of that being highway because the owner lives away from a large city. As long as everything checks out is it a worthwhile buy? Any major mechanical things I should pay extra attention to? Any thoughts or advice would be great. I currently have a 2002 VW Jetta thats running ok, but things are starting to act up and the more i read its common.
