It's a substitute for not being able to go to Beaulieu, and I know it'll be smaller!
Partly a day out and I have a few bits of trim that have seen better days. If I spotted these bits the trip is worth it but also like the idea of browsing for inspiration. For example, I'm fairly sure the switches are same size as a car I used to own, so the idea of having a replacement set, with non-faded graphics and a fresher look appeals.
And yes, the idea of paying to spend money feels wrong. I don't pay to enter a shop so why should I to enter a computer fare, antiques market etc.
Just go not expecting to find any Lancia bits and if you do it's a bonus! Also if you need any nuts bolts fastenings and general consumables make a list before you go, I never do then can't remember what I need! Tools and bits n bobs can be very good value. The range of stuff isn't as diverse as you would find at Beaulieu
