1/24th scale Ferrari Dino road car by Joel, it is a plastic kit by Fujimi, motorised with a very small motor from an HO slot racer and fitted as a sidewinder, you can just see the drive gear through the suspension, this is the most discreet conversion I have managed so far

The guide is monted on a Scalextrix guide block, as used in the F1 cars they made in the 70s

The complete interior has been retained.
