I know the guy selling this, he's a member over on the 190 club. Sold him some rear lights a while back.
He put a lot of work into this, a mature gentleman who owned a garage/worked in the trade all his life.
Although I've never seen the car in person I've seen some of the build pics. Looks like a decent job to me, I think the advert listing will not be doing the car justice. Probably worth enquiring if seriously interested
There was a magazine feature on this car recently too - can't remember which one though!
In all honesty it's not a bad thing that it's not all MB. For me it's a bonus as mods such as a v8 and coilovers alone are much better than standard could offer.
