 Never buy a mercedes unless you want to overpay for a completely unreliable vehicle. Buying one is like losing money, and keeping one is like throwing good money after bad! I bought a brand new 2009 E350. Six months of ownership, and 3 problems, 2 trips to the shop, 1 tow, 1 battery recharge...and worse of all, tons of aggravation and frustration dealing with  Mercedes Benz.
