They'll definitely try and sell you a payment that sounds great - make sure you calculate out how much you're paying for the car total before committing. Might be great for the first 6 months with a reasonable payment but not so cool when you're buried in the car for the rest of your life...

Nice people - my buddy bought a Mustang from them back when we were in college. As with any used car dealer I would have the car inspected for previous repaired damage/frame repairs/paint work, etc. before buying...

Good luck
