This is a 28 mm post-apocalyptic car sculpted by Dave Stone at Wargames Terrain Workshop that sells for the princely sum of £6.
Suitable for lots of uses, it comes with a firing platform on the back that can take a mini on a base.

I chose to paint mine in reasonable condition but Dave's website has one really dirted and rusted up.
Black Maria
This model is available from WTW for the sum of £5, and includes the guy with the multiple rocket launcher in the front boot space.

Again, Dave weathered his display model rather more than me.
Grav Car
Finally, I bought one of these little beauties for a fiver. It's a Lamborrari 2000 sports car for sci fi skirmish games.
There must be a couple of hundred different sorts of resin models on the WTW webshop, all at highly competitive prices.
Well worth a visit.
