I am considering the purchase of a 2007 corvette coupe.  Is it normal to hear creeking and rattling inside when going over bumps or simply pulling into a driveway?  It's not the removable roof, but rather the back window.  Are there other known problems that occur with the under carriage that would create knocking noises when going over bumps?

It shouldn't be making noises like that, something sounds fishy. The C6 cars are known for their solid construction and lack of rattles compared to earlier Corvettes like the C4 models. Could be the hatch on this car isn't fitting properly.

It's possible this car might've been in an accident and repaired. Before buying, see if the owner will let you take the car to a shop and have it put on a lift so you can get a look at the underside of the car.

Take a close look at your springs. My 99 Audi A4 had a creaking rattle that happened when I went over a speed bump or dip in the road, and it turned out the bottom of each rear spring was broken. I replaced them and the noise went away.

Another possibility would be the sway bar end links. Since the sway bar is worked pretty hard, the bushings in the end links will wear out eventually. This can cause some clanking. Look behind the wheel hubs - you should see a short bar or bracket attached to the hub at one end, and to a bar at the other end. The bar will go forward or back a short way, and then across the bottom of the car to the other wheel hub. That's your sway bar. The bushings in the end links (the short attachment bars that anchor it to the wheel hub) or in the body brackets (some cars bold the center of the sway bar to the body with a bushing in a bracket) could be deteriorated and allowing the bar to bang around on the body.

Finally, take a look at the suspension itself. Do any of the bushings where various parts meet appear to be cracked, leaking fluid, or gone entirely? There should be no gaps between any suspension pieces at the points where they meet. If there are, you're missing some bushings and may well have found the source of your nois
