Yes, I have the roof, windshield, heat, winch, bumper, after market tires and rims, metal tailgate bar, and added a sound bar on the inside, rearview mirror, spare fuel tank, and had to add a rear license plate light to make it completely street legal in our state. I also bought an additional spare tire, which I'm glad I did because I had to change it already from a rock piercing the wheel.
Mine had a lot of upgrades and after market stuff added, so it ran me around 33-35K.
The full hard cab enclosure with installation is the most expensive part. I would definitely recommend spending the extra coin and getting a side by side with a full hard cab and heat. It's a life saver when you are deep in the woods and a storm decides to hit, plus if you live in an area where it get's in the 10's, 20's, 30's, etc...the heat is a must have in my opinion.
Also, If you plan to go through a Honda Dealer...I would suggest getting the platinum plan. All of the services are paid for (they need serviced every 600 miles, so if you plan to put some miles on it....it's worth the extra cost per month). They also prioritize you. Faster service, 2 day turn around, and not having to wait weeks for a service. I live in a town where a lot of people have side by sides, so being able to get it in and back with hardly any wait is a plus.
