yeah except open to the elements with no ac or heat. If you go no AC you might as well buy a classic jeep you could drive on the road.
but I see the appeal.
I think that is close to the cutoff for not having def. It wouldn't need much since it is an off-road vehicle. Not ment to run 70mph down the highway and have a 3 second 0-60.
I've seen one on the road but most counties and cities around here allow side by sides now. They make you take a second look but look like it should be a DIY kit.
