Unique toy for car loving 4 year old

[Mallowmarshmallow]

Hello all

A friend's son who we buy for is 4 and loves cars, I'm wondering if anyone can think of something car related that's a bit more unique so I don't get him a duplicate. My budget is around £10.

When my son was 4, he was really happy to receive a model of our car (a VW Touran) to go with his collection of more exotic toy cars like Hot Wheels and Porsches.
