Pictures as requested

The other vehicles are a Mantic pickup truck and a Tamiya 1/48 Japan Light Armoured Vehicle. The figures are the Hasslefree Post Apoc Scooby Gang. I am planning to buy the non-apocalypse ones, assuming the Hasslefree website ever comes back up

The Van has a windscreen but no side windows and is held together with screws

(I hate rivets, it's almost like they don't want people to modify them)

Fred's head is level with the bottom of the side window, so it's definitely a climb into the van. The other dimensions are fine, and the height isn't glaring. I usually go by the seats and steering wheel and those are fine. Overall, I'd put the model at 1/43, definitely not 1/32, and fine on the table. It has the added benefit of having all the decals, which is the bit that stumped my own plans
