Looking to buy a new or slightly used mid sized car year 2009-2011. Price range 30-40,000. But I need a good forum to ask about stuff like which one doesnt cost an arm and a leg if something breaks and which has the least amount of problems. Looking at either a Cadillac CTS, BMW 5 series, Mercedes C class, Audi Q5, or a Lexus ES. I tried the major car magazine websites but none of them had forums that I saw.
