What does history have to do with anything? You asked for advice and was given just that. As far as history goes German cars have a history of unreliability and being very expensive to repair but the fan boys always go back for some reason.
As I said a 30 year old (at best) Benz is going to one of the last things you want to daily drive. If you are dead set then be my guest, but don't ask for advice then say you're going to do whatever you want.
