I have found interesting 2009 Ski-Doo 800 Adrenaline but with 121" track.
How complicated and expensive is upgrade to 137" track ?
Mostly I use snowmobile off trail so 121" might be too short.
Last year I had problems with my Polaris in deep snow
I have found one more - AC F8 2009 with 136" track Price the same as Ski-Doo 600 E-TEC Summit with 146" track.
Ski-Doo is convincing me with Rev-XP platform where I can mount additional seat and occasionally take my daughter for a ride. Arctic Cat doesn't offer such an option.
