Hi kezo
From memory I think you get a free cup of tea and a Motability pen to fill out the form to enter your chance of winning an iPad… oh and a key ring from Brig-Ayd.?
The only thing that useful for myself is the ability to drive cars with adaptions though you’d be very lucky to get one in a car of interest and having turned up at the Exeter show a few years ago 4 or 5 hours before the close of play all the slots for driving an adapted Ford Kuga were taken for that year.
It’s not to bad a day out if you don’t have to travel far but like you said with today’s fuel price its not worth, in my case, spending £40 to £50 worth going to a show. That said with the Exeter one I just happened to be passing the show that weekend on the way to my holiday and that was the last show there before the 2 year close down.
