all being said the car is in very good condition and rare to find with the Webasto roof. Now, who is the target? A Mercedes lover and normally they know everything about the model so before getting it on sale do the following.
Change that white/orange light in the front, turn upside down the right rear light, repair the back drivers seat and get rid of that radio, either install an original one or just one of the radio wood panels with the 220s logo on it. The left fog light looks like is not the same colour as the right one
Don´t be in a hurry to sell it, who is looking for it will pay big bucks, also try to advertise it in Germany (mobile.de ? Gebrauchtwagen und neue Autos ? Deutschlands größter Fahrzeugmarkt.
), they reach all europe and you never know if there is someone interested on it.
