If I had the kind of life in which safety, gas mileage, acceleration 0-60 in under a quarter minute and highway driving were non-issues, I might find myself searching one of these out.
Introduced to the mass market in 1973, Volkswagen's "Thing", otherwise known as the "trekker", the "safari" or plainly, type 181, was slightly more than an 46hp flat four engine, 4 seats and a speedometer. Doors could be removed, the windshield folded forward, the interior hosed out and heat was provided by an optional gas-powered heater that connected directly to the fuel tank. VW sold it as less expensive peer to the then popular 4WD Toyota FJ40 Land Cruiser. (Uh, no.)
Perhaps wisely, importation of these beasts was halted after 1974.
My friends eccentric father proudly owned one when we were kids and I can distinctly recall the overwhelming (i.e. suffocating) smell of petrol and the fear of the floor boards opening up like an upside down sardine can when riding in it on the way to school.
