This is one of the car show highlights of the year as events at knebworth go back decades with rock concerts and car shows and is set in a fantastic location also right next to J7 of the A1M, its simular to a Battlesbridge/Uxbridge style show but better as its full of supercars/custom cars and vintage as well as huge club displays costs £8.10 per head and you can book online

In the past I have seen many celebrities at this event from music, movie and TV

Bank Holiday weekend. An enthusiast’s paradise with thousands of cars on display, autojumble stalls and lots of cars for sale. Live commentary and arena displays of clubs, kit and custom cars. Pre- and post war classics. 10% discount on admission tickets for online bookings
