I don't regret my 2009 Brabus purchase one bit....(1000 miles)......
I have a 560SL, a GL320-CDI and a 4 door Tacoma Pickup (lwb-4wd).....this smart is every bit as good as the other three cars......
you have to understand, only a tiny percentage of the total ownership out there posts problems here.....and usually they are relatively small problems......
the quality of this car is first rate (mine anyway).....I just wish the Brabus came available with the turbo diesel.......sigh.......
