Matchbox 36c; Opel Diplomat

The Opel Diplomat with its opening bonnet was released in 1966 with black plastic regular wheels, there are a number of different boxes for the regular wheels versions showing with either light or dark green cars when the car in the box is always gold. These don't though have a significant effect on the value. There is a turquoise regular wheels version quoted by some authorities at very high value which is probably a pre-pro prototype.

In 1970 it was converted to Superfast and remained gold in colour. Light gold ones are hard to find and attract a premium. Some Superfast models have silver painted trim, some do not but this does not seem to affect the value.
