Crap car rentals for film-makers.
Period dramas & films only seem to have showroom condition vehicles in them. For verisimilitude, they need to be able to hire rusty old hulks from all dates, 30s to 00s. Like what you used to see on the roads for real. Most of them won’t even need to be runners, just immovable props parked by the roadside.

Buy some land, put up some security fence, CCTV and controlled access gates, then rent caravan and motorhome storage space @ £350 p.a. ea.

Currently looking for somewhere near home and everywhere nigh on full, each with 100 – 200 vans on there – do the maths!! 😛
