Where to take car-mad 5 year old near Oxfordshire

[fly]

Will be in the Oxford area for a few days next month with a car obsessed 5 year old.
Is there anywhere within about an hour's drive that I can take him that'll be of interest? I guess the ideal thing would be if we could spectate at a track where he's likely to see supercars, etc

National Motor Museum at Gaydon?

MINI factory

On the fringes of your time requirement, but the transport museum at Coventry is brilliant. Very easy to get to from Oxford.

Bourton on the Water has a small car museum

Caffeine and machine for a juice?

Another one that's a bit further away, but worth seeing if there's anything on at Prescott Hill Climb (near Cheltenham). Can get right at the side of the track in places for spectating, lovely setting too.

The silverstone experience?

Mercedes Benz World at Brooklands isn’t that far away

Brooklands next door is much better.

Obviously none of these tick the box for moving supercars. For that you’d need a Trackday at a circuit.

Castle Combe circuit?
