My buddy is looking at a few new to him sleds. last year was his first year snowmobiling and he rode a 99 skidoo formula 500fan. he is looking at a 2003 skidoo adren 500 with 3100miles for $2400. Hes not sure of the new style sleds as he rode my 09 polaris shift 600 last year and my bros 09 yamaha nytro and did'nt like the high sitting and tippy feeling. He rode my wifes 06 polaris indy 500 and loved it. It rode better than his 99doo but not the high seating of the new ones. The sled i would like him to look at is a 03 ski doo rev 600 with 4200miles for $2900. What do you guys think is a better deal since I really don't know a hole lot on the doos. I think the 500 did'nt have many problems and I'm not sure of first year run of the revs. Any input would be great.
