Good luck with your search!...When the M235's are underpriced like that, you have to jump on it...Anything under $45K (depending on mileage) is considered on the lower side of the used price range.
To be honest I wasnt even looking for a car when I bought my M235...Saw it in Autotrader on Sat, signed my cheque for it Monday. It was a dealer demo with 2700 on it - full warranty
