This model was only around for a short period before being replaced by a Whizzwheels version. So it is quite scarce and you will find that there are very, very few indeed which still have an original aerial intact on the roof.
This is, therefore, a scarce item that may well be missing from your collection. Check also the logo on the bonnet. Early editions had a Ghia logo and later editions had the De Tomaso T logo. This is the later edition.
There are two types of engine block too and this has the steel type.
This is in excellent condition all round and the box is also very good with no parts missing, although the elastic band retaining the chassis has been replaced.
