I would check the blue book value and make sure you're not paying too much, and double check with Ford on the "recall".
There's a forum here specifically for 2005 - 2010 Mustangs, and I'm sure the guys over there would know the answer to that question as well.
Other than that, if you like the car get it! It'll definitely be more fun than a Corolla (was my first car). And, actually that year range (and the v6 at that) was the model I got for a rental once that really got m desire for a mustang stirred up again. Finally was able to get one in 2010 (2011 GT).
Welcome to the Forums, look around and enjoy the Car!
Let us know if you bought it!
