My first 500CL was much like this. I used it and learnt a few lessons from it before deciding I liked the model and spending kind of proper money on a very proper car. I'd be wary of someone who only puts the ignition on part way to show the sat nav and nothing else, one of the things it could be hiding is the little red LED by the air con which would be a problem but there again, there're so many things to check. Just from a personal pov, I'm not a fan of cars that have been made to look something that they're not, CL55 badges, AMG badges, quad exhaust tips etc just don't belong on a 500 CL. It's not dear but don't spend all you have as you WILL be having to spend money on it. Oh, nearly forgot, I was a car dealer for five years, the ad screams 'trade'.
