This is a scarce item. It may be Whizzwheels but it is one of the better Whizzwheels as Corgi did a good job with the Mercedes Benz 350SL. You will find plenty of metallic blue and solid white editions and pretty much as new at very reasonable prices still. This metallic green one, however, is very unusual.
There is a range of box types, too, starting with the red and yellow type (with or without the Technocrats addition) and through to the black 'rainbow' type as this model had a long run from 1972 through to 1979.
During that period the wheels also got changed and you will also find some darker shades of blue with a more solid and shinier style of wheel, similar to those on the green edition shown here.
With prices for most editions low and lots available in excellent condition with quite a few variations these can make a nice collection that should not break the bank.
