Looked at them years ago. Not real pleased with the changes in the front sheet metal, after the Jeep lawsuit, but that's personal taste.
Don't like the lack of a tilt steering wheel. If it fits you, no problem. If it doesn't, you're stuck dealing with it.
There used to be an auto trans option. It was only available for a short while. They apparently had lots of issues getting it to shift at appropriate times. Don't think that's available, anymore.
The suspension is leaf spring with solid axles. There are some lift kits/aftermarket springs available, but it will NEVER ride like a UTV with independent suspension at all 4 wheels.
The engine and manual trans seem solid, per most reports.
My take?? If you're gonna stay on smooth trails, or really want a "jeep", it's pretty neat. Essentially a brand new Willys Jeep ('40's/50's), with a diesel engine.
If you want something that will go faster, SMOOTHLY, get you a Polaris/Can Am/etc.
Also, if you haven't climbed in/out of a Jeep multiple times, in the past, TRY IT before you buy the Roxor. Sounds picky, but you have to step over the side of Jeep/Roxor (there's that 5"-6" "rim" to deal with). Not a big deal for everyone, but harder for older folks, and a REAL pill if you're constantly getting in/out to check fences/feed cattle/whatever.
Hopefully, someone will come along to give you more DETAILED info, than this, but these are some things to think about.
They were $15,995-$17,995, or so, when they first came out. Like everything, the price has gone up substantially in the last 2-3 years.
If I had a 10,000 acre place with finely graded oilfield roads, it'd be cool as hell. For something to have at a smaller property or for bombing through rough fields of mesquite/cedar, the smaller utv's are going to be more suitable and a softer ride.
