I hit the submit button before I wanted...(wiping kids arse!) was going on to say as there are cars out there that looked so good when they were made that you do not need to do much to them to get them to look good.But what could be done to make them better bring them up to date,like a fantasy type thing.
I would possibly source a later model Mercedes V8 and and do a motor swap.New coil overs brakes and mechanics fresh leather interior and leave the cosmetics to just a stanced drop w wheels.
I have also had a thing for the old CSI,s too.
