Hi everyone, newbie here. I have been around quads my whole life and owned several rzr's, lastly was a 2016 900s. After my wife and I had our first child, I sold the rzr and now just have a quad, Suzuki King Quad 750. I have two girls, 3 and 1, and they absolutely love my quad but it is hard to ride them on it and probably not the safest thing. I have about 5.5 acres and live in a somewhat rural area where we can ride the roads. I think the teryx4 is perfect for me. Maybe trail ride, Royal Blue or Windrock every once in a while but nothing extreme, use it around the house for brush and just have something for us to cruise on. I am looking at 2016-2020 models, trying to find used ones. I remember older models had their share of issues with oil leaks and overheating but the newer models seem to be really stout and reliable. I know 2016 included updated interior and exterior from the previous year but are there any changes from 2016-2020? If so, I cant find any on my searches, other than paint schemes. Secondly, man the market in Kentucky has changed. Used models, if you can find one, are really expensive and I cant even find a new one to take a look at. Other models I am interested in are the Pioneer 1000-5, but I am not crazy about the transmission. The Wolverine X4 is another, but I dont like the back seats as much, cant imagine those tracks working very well after a while. A couple questions, any common problem areas to look for? Is the heat and noise really that bad? Other than top speed, is the power adequate? I was never lacking for power in my 900s, but I am sure it wont run like that. Thanks for any input guys!
