Well, if you get it, have a tech take the valve cover off and check the wear on the rails. Then you'd have a better idea of what's goin on there. The dent will be on the roof, between the sunroof and the windsheild. Some more things to check will be subframe bushings (those are spendy) and the front sway bar links. If the car has been driven hard, they'll probably be broken from the strut casings.
