I currently have two 451's, a 2008 coupe and a 2009 cabrio. They are both silver with black tridion. I am wanting to change the panels on both to the 2009 red (rally red I believe) but want to keep my current silver ones. It may be too expensive though to do it. At one time back when the fortwo came to the U.S. it was told that a full set of replacement panels could be had for around $1500. I don't know if that is still true or if it was ever true since I never checked into replacing mine. Or, I could consider just having the ones I have repainted I guess if the price is too high on just purchasing them outright. Also, I think you also have to get new fastners as well? Anyway, any suggestions?
