We have not been before, but we are going to have a stand at this show which is just south of Bourne. In 2017 they had 1000 vehicles, and over 6000 visitors, so sounds very interesting. Their website is HERE.
Entry is free for the driver and 1 passenger in each exhibiting car, and you need to arrive on site between 6.30 and 9.30, and I suspect you will not be allowed to leave until near close of show at 4pm, which given the numbers of visitors is fully understandable.
Mark Dakin has kindly agreed to manage the bookings, and you need to book with him by the 10th June 2018. He will need from you the following :-
