I still very happy and impressed with mine. I bought my HavoCat when they came out after test driving every other comparable rig, the Havoc was just “better”. I certainly wish that I could have gotten it at the price you can now, but still.....
As stated by others, most issues were either recalls that should have been dealt with, or just annoying ones that aren’t catastrophic. What most folks don’t like is the lack of “aftermarket modification” stuff like portals and lift kits. I bought the Havoc because it already had basically what I needed and the extended cab is great. I could buy a different machine, but then I’d have to spend $2-3k (suspension, lift, etc) more to get it to ride as good as the Havoc does stock.
The default seats in the Havoc kinda suck but there are several options for either DIY modifications to make them better, or replacing them all together. (and they do get better after putting some miles on them). If the rig is brand new, follow the break-in instructions to the letter. I know how tempting it is to just jump in and hit the throttle, but trust me; it makes a difference. The stock tires are almost worthless in sludge-mud and will become slicks, but they are great on almost everything else. They are not DOT certified though and they cause a “wobble type vibration” at speeds over 50-55mph because they aren’t balanced. If you want to go fast, change the tires.
Roofs, radios, mud flares/flaps, windshields and back glass are all available for these rigs and you will want most of those. Lol. Anything else is just icing on the cake. Good luck
