2015 rzr 170

A buddy of mine is thinking about getting a 170 for his kids. My questions are his kids are 7 years old and was wondering how long do these last for a average age? Also is 3700 out the door a good price for one that has 4 hrs on it. Sorry guys if this has been asked a lot just trying to help a friend out. Any help much appreciated
