Looking to trade a C5 convertible in on a 2001 XKR convertible. The XKR has 10k miles on it and is warrentied for 6 years/ 100k miles. They are asking mid 50's for the XKR and are willing to give me 28k for my C5. What are the problem areas in the XKR? Anything to look out for? Any problems with daily driving? I think it is stunning and I know it is tight inside but it will be good incentive to lose some weight! Thanks for any feedback!
