Lexus

I finally got a good paying job and want to buy a good hardtop convertible. out of the lexus sc430 or mercedes sl550 which one is better and why? i live in hawaii and i plan to keep the car for at least 8 to 10 years if not for the rest of my life. any other hardtop convertibles like this other then the new bmw one thats luxury/sport. (not miata or sebring etc)

They are basically the same. the lexus would last longer. the mercedes will probably be more expensive to fix. it all depends on how the drive is. test drive both cars and see what you like to drive more.
