FWIW, I got a 2002 Polaris XC 500 (liquid cooled Liberty)and a 2002 two-up Yammie Venture 600 (liquid cooled triple) before last season. Both are great starting, great riding sleds, but the Polaris takes longer to warm up.
The Polaris is also more for “go fast” use. My wife loves the Yammie. Electric start, reverse, infinite thumb and hand warming settings as opposed to just two on many sleds.
The Yammie rides the trails great, electric start is nice, but on a two up reverse is necessary, IMHO.
I would like the Polaris two-ups with the 500 liquid cooled engine and reverse also, and electric start would be a bonus.
I got mine and they were showroom floor clean, and with a covered trailer, for less than a new sled. So far so good for me, I am looking forward to snow and pulling the shack around with the Yammie, and hitting the trails again Wife and I had a blast.
oh yeah, I traded a canoe for an old 88 Polaris indy 400, and it runs great and is a great ice fishing sled or extra for the kids or rookies It is so much lighter than either the 600 or the 500 that it is almost funny
