Your seat track problem is common on the C5. They make kits that you buy to repair the worn out part to keep your seat from rocking. If you’re not going to drive with your chin spoiler attached, watch your temp gauge to make sure you don’t overheat. The center piece of the spoiler sends air into the condenser.
How would you feel taking this car longer distances? Like a 250 to 450 mile road trip each way? I've seen in the forums that people have done this but I would like your opinion.
