Guys, I appreciate your input. There are so many conflicting stories out there that it's hard to know which ones to believe. Last year I bought a 2 owner 2005 CL500 with 45k on the clock for $13,500 all books and records and a previous CPO car. I've put about 6k miles on it and so far so good. I'm keeping my fingers crossed,, have put some money into prev maintenance and wear items but that's about it so far. What are your thoughts on a clean, low mileage 2006 s500 with a good service history. Or should I just look for something a bit newer. Thanks for taking the time to respond.
