I'm not an expert, but in the USA the 735iL isn't a rare car in itself. Probably the important part is the condition of the car, and the durability and popularity of the color combination. Some colors fade or wear worse than others. Some colors look dated compared to what's popular now.
Depending on what the car needs to get it running, it's probably not even worth that unless you plan to part it out.
