This is a truly amazing scale car, it was based on a Tonka Polystil 1/18 model of the original Lamborghini Diablo but taken one step further by Europ'Or as they gold plated it.
This white Lamborghini Diablo 1/18 scale by Bburago was actually a hand painted special edition. Bburago never offered this model in white over a brown interior.
Back in the days these 1/18 Bburago models were about the only ones you could find on the Lamborghini Diablo, this Copper metallic one is one of many shades.
