If some bank would lend me the money, I think I would buy a tank for travel through liberal areas. (and have a sign that says, "I support the second amendment!")
I was seriously thinking of buying an armored car as a traveling vehicle and as an investment. British Ferrets were going for about 6,000 dollars. They have Rolls Royce engines and the overall condition on the vehicles was very used and poor. Replacing belts and hoses and wiring wouldn’t have been a problem. Replacing brakes and gauges would have been but not impossible.
Rusting out the body and frame was impossible so was worrying about fender benders.
What stopped me was overall comfort. Driving that thing for anything other than short trips would wear you out.
