I'm guessing average age will be early/mid 30's because they'll have the wife riding shotgun and two kids in the back. Younger than that and people will want more power/weight and older than that and the kids will be on bikes or quads.
Just turned 32......I didn't like the idea of adding an extended cage to my RZR for the kiddos...all the companies I asked, was that if they have done any roll over testing and all the answers were no...
So the best option was to buy the new RZR 4 and strap them in.
When we get the new cage and roof it will be 100% perfect!
