There has been a HUGE Sand Rail/Buggy culture in S. California for 40 years or more. Started with VW converted bugs, and went up from there. Now most places for them to ride near the City (Lost Angeles) are closed.
So you see some great, cheap deals on all kinds of buggies and sand rails, some of which are truly amazing vehicles. Nothing like a Quad really.
Some of these things are Trick. Reliable, stable, FAST, not four wheel drive
(you don't need it), carry luggage, cooler and a passenger side by side. Seat belts, roll cage, big tires, beautiful wheels, trick suspension. You still see them in Baja.
