I'm just trying to figure out what my wife's Sidewalk mini worth. It's a 2007 Convertible, Black and only has 18,000 miles. It is automatic but has all options. Cold weather package, sports package, etc etc etc. Garage kept and still under factory warranty and service contract.

Looking for advice as we may decide to sell it. Deciding which car to sell between the Mini and my 07 BMW 750Li to make room for a new toy.
