Some backround. I am going to college next year and have been working towards a MB purchase to replace my Camry. I have decided on a W126 and am leaning towards a 300SDL or SD. But I really like the 560SEC's. I talked to the insurance agent and it costs the same to insure an SEC as the SEL. (3k a year) So here is my queston what does a 560SEC in good condition with say 100 to 150k on the clock cost to maintain? What kind of gas milage can I expect? I am looking to spend about 7-8k on this car I think I can get a good one in this price range. Also what about the 500SEC's are they similer to the 560's?
