06 Recon ES

Okay for all of you experts out there and Recon ES or ES owners. I’m looking into a purchase of an 2006 Recon ES version atv. I know absolutely nothing involved the ES versions and I’d like to know what to look for involving it. I really don’t know what questions to ask the seller. The pictures look clean and it doesn’t look abused. Was the 06 Recon ES a good year or where there issues. I know that the 96 300fw had an issue of the rear going out. So I was just wondering. Anyway, any help with the ES issues/questions and also what would be a good negotiating price to begin with and what price I should stick to my guns with. Thank you for the help and time. Jack
