You're right. The wheels and tyres are real. But to build a full size McLaren must have taken them months, if not years.Are the wheels and tyres Lego too? Doesn't look like it, but impressive anyway!
Great collection of well-known race cars. But the Lego McLaren is insanely good.Ah, a Senna McLaren - seen plenty of those at Donington (when it had a museum).
Cosford & Duxford are well worth visits.
