New RZR 170 Clone- Avenger 150cc- Blades 150cc

I bought my kids (4 years old and 2 years old) a new UTV so they would be able to come out to the desert with me and enjoy the outdoors. I am a paranoid dad, so I didn’t want to get them a dirt bike. I like much more the idea of a complete roll cage protecting them. I was considering the Polaris RZR 170, but seeing that it was 2 times as expensive and doesn’t look nearly as good and lacks so many of the features this one has, I decided to save the car goes about 25-30 mpg.
