Brooklands was the world's first purpose built race track, and is now a museum for cars, bikes, cycles and aircraft (with museum entry prices).
Best check the website for costs, further info etc and especially the parking arrangements as the address on this post is for prob for non-event visits (small car park), whereas 'events' such as this, a well signed (large) car park (The Heights) is used to cope with the visitor numbers.

Each year they have a motorcycle day which gets pretty busy with classic, vintage and modern bikes.

Brooklands is a mile or two from the A3, in the vicinity of the M25 J10.
