I'm looking for a used Speed3, and I've found one a few hours away that is at a good price. It's an '07 GT with 15K miles. For someone who's new to the Speed3, and new to Mazda's entirely for that matter, what should I be looking for when I go see it?

If the person has been beatin' on the poor thing ( and who wouldn't want to? ) What should I look for? And what kind of problems are these things known for?

If these cars are prone to any particular problems, aside from regular maintenance is there any recommendations to prevent them?
