This was for sale on PistonHeads a few months ago, and discussed on here at the time.
I commented that they are extactly the same as the vents on my parents Range Rover Sport.
It's horrible! It needs some period AMG alloys. Also the gearbox knob and the AMG badge on the centre console does it no favours!
This probably won't be a popluar comment, but I'm not liking that AMG duck tail spoiler. If that's present, it needs to have the rest of the kit, IMO.
