I have a black 2006 Limited roadster with 43,000 miles, I bought it as certified used car in 2008 with 14k and don't have any problems now but i am glad I think I'm glad sprung for the extra $2,000 fro the extended guarantee which covers me thru Chrysler till Dec 2014 or 80,000 which ever comes first. . I was afraid of a big ticket expense like the conv top you mentioned. Has anyone used the extended guarantee thru Chrysler?
