Love my certified C430 cabriolet! It is a beautiful black opal, black clot top and ash interior. The Bose sound system is 2nd to none and build quality is excellent. I do believe this is an instant collectible and will only increase in value over the years. The big 4.3 litre V-8 gets over 25mpg on road trips and the comfort is superior to any other convertible out there. When the top is up you would think you where in a hardtop coupe. Probably the most beautiful car I have ever owned. If you are looking for a high quality dependable used convertible, I would strongly suggest one of these!
