I have three Rincons, an '03 I bought with 150 miles(!) for $3900 in 2014 (it was from an estate sale, had been sitting for 8 years and the estate's executor had it completely serviced from the local Honda dealer before putting it up for sale), an '05 I bought for $3500 in 2015 with 4000 miles that recently had the cam chain replaced by a Honda dealer, and a '12 with 900 miles on it I bought in 2015 for $5000, with a brand-new Warn 3500 winch installed. I've put new batteries (and Battery Tender pigtails), and new Maxxis Bighorns, on both of the 650s. I had to put a new set of rear disc brake pads on the '05. Neither of the 650s burns any oil, and they both run really strong.
I got the second Rincon after we found the Recon ES I bought for my son simply wasn't the right ATV for riding the steep, rough, and rocky trails we like to cover in the eastern Cascades. As I was selling the Recon, my wife asked why we weren't keeping it (after bugging me to sell it), so she'd have something to ride... hence the third used Rincon.
I like having one model of ATV so that oil, filters, and servicing is simplified. Yeah, I know the '12 is fuel injected, but I couldn't pass it up for the price. We'll see if my wife is serious about riding with us, otherwise the red '05 will be sold and my son and I will ride the green '03 and '12 Rincons.
Rincon's seem to hold their value really well, at least here in the Pacific Northwest... and so do other Honda ATVs. I was thinking about picking up an '06 Rancher 400AT with the Hondamatic with less than 1000 miles on it and VERY clean, but the owner sold it in a day for $3500. There's another '12 Rincon in the region, with a Warn 3500 winch and aftermarket wheels and tires, listed at $7000, with less than 300 miles... and a local dealer has a brand-new '14 Rincon listed for $7300.
Hope that gives others some idea of the prices for Rincons, new and used. The only Rincons I've seen for less than $3000 were high-mile beat-up ATVs. I just saw one sell on eBay (not in this area) for $1600 with more than 8000 miles, a known mechanical problem with the engine, and damaged plastic and seat.
