If you Google each one they all seem to be in the $5000 range for a run of the mill, average vehicle. The Lancia is probably the sexiest of the bunch if you like that styling (not my cup of tea) and there's a very clean, rust free Arizona car that popped up for $6900 asking price. The little Opel's were very common when new, and were not seen as quality cars but more of a toy or lady's car as I recall. Value is an individual thing, to each his own and let the buyer beware, right? Unless they are pristine I'd say he's got the right asking price for the bunch as a seller, with lots of room to negotiate to their true value.
