I was considering buying a new Sporstman 570 and the dealer strongly suggested that I buy the new 550 instead. He said the 570 is just a punched out 500 and has the old frame and suspension. I realize that the 550 has power steering and upgraded frame and suspension but it is also considerably more money. I live in Salt Lake City and I can buy a 2013 550XP eps for $7200. Should I go with that or get a 570 for about $5400 instead? Why is the 550 so much more expensive. Are either made in the US?
