The car is fundamentally very nice - a 560 SEL, well optioned with the very rare split rear seats and a good colour combo too.
Just needs to lose the AMG mixing of skirts, wheels and rear bumper....if it wants to be a Carat then Gen II Carat versions either maintained stock skirts or utilised Lorinser versions. Front Carat bumper is great, genuine Gen II version.
I have the genuine Gen II Carat rear bumper lying in my back garden should any current or future owner want to get the full carat look.
As the car currently stands, it'd be easier to make it a full AMG using a stock w126 bumper and the AMG Gen II front splitter. I can't see anything Carat specific about the interior ?
