New to Kawasaki- considering a Ridge Crew Platinum

[Papa Hoc]

Good morning to all and thanks in advance for your time. My wife was smitten by the Ridge Crew due to the front doors opening normally, and the fact the passenger seat adjusts. I liked the idea of a 4 cylinder and what looks like a great cabin layout and 8 speaker stereo. We have a Polaris Ranger 1500 2 door and despite its clunky drivetrain and some quirks, it seems to be a rugged, capable machine, and with the Aftermarket Assassins tune/ muffler makes 150 hp. This one would be a second machine as we are buying it primarily back and forth to local stores on 35 mph roads, rides around the neighborhood with grandkids and dogs, and some very light off-roading. My main concern is the engine noise, cvt belt life, and cabin noise at cruising speeds of 40- 50 mph. Can this model accelerate to say 40 and maintain that speed even on slight inclines without a lot of drivetrain/ engine noise? How quiet is the cabin at a steady 40 mph? Does the stereo sound as good and loud enough as its 8 speakers imply? What is the drive belts life span and can you damage it by consistant hard runs/ use? Any other usefull info is also welcomed!! Thanks in advance!
