Hey guys and gals, I posted this in the general polaris viewing section but it is very hard to find there so I thought I would ask in the pro section. I'm wanting to get back into sledding and bring my family in with me. I bought new sleds before but never used! I'm wanting to get 2 rmk's and 2 340's. My question is what are the main things to not miss when buying used mountain sleds? Around 1000 miles+/- a little. I'm thinking a 2009+ D7 and D8 or a pro 600 and D8 or pro 8 for my wife and I. I want to get the best sled I can for her so that it will be fun and get her hooked like me! Thanks for any advice.
