Silver is the common colour, black is the exclusive colour.
Bargin? Not sure.
Yes, it looked like a fine example, but over the last few months we have seen a lot for sale, and I dont think many have actualy sold (as appossed to being advertised) at a lot more than that.
In my opinion, that is a realisitic price for a generaly good condition Brabus at them moment.
Obviously, if you wanted one tommorrow, you would have to pay through the nose or wait around until one came up. However, if you said you were going to spend between 4 & 5 k, if you waited for a few months, one would come up.
If you own one, that may or may not be a slightly depressing reality, depending on when you bought it & how much you paid.
