W123 230E Purchase advice

Hello guys, I’m new here and I have a direct request: Since I’ve been looking for a car for a long time and I like a W123, W124 or W201, I’d like to ask you for advice. I came across this green W123 230E on my daily internet search at mobile, autoscout, ebay etc. I don’t want to ask about a model consultation, because I think I’ve informed myself extensively about the series, but much more about a purchase consultation z u this special offer: Mercedes 230E W123 I have already looked at several cars, more or less in the vicinity, and I have come across a lot of dealers and sellers and have partly had very negative experiences. With the above mentioned 230E my problem lies in the distance which unfortunately amounts to more than 600km. And since I do not want to continue to pay hundreds of (T)Euros for petrol and can and I generally lack the time to travel all of Germany on the search for a car , I want to hear your opinion before I get on my way. Maybe there is also a expert person from the area of the car who would be willing to look at the car for me (I hope I don’t do anything wrong here or violate any rules, and if so, please kindly point out (: Thank you in advance
