I was all set to buy 09 M8, but deal fell thru. Now I have four other options 2008 M8 SnoPro 153 for $7500 or 2009 M8 SnoPro 162 for $8800. Also 2008 M8 standard 153 for $6900 or 2008 M1000 162 for $7300. All are brand new. Are there any issues with one model over the other or a nagging problems with one model? I was leaning more towards the 09 M8 SnoPro, but are there $1300 worth of improvements over the 08 SnoPro. I will probably only get out west a couple weeks a year. Mostly just boondocking not so much highmarking. Will be putting on pipe, venting, clutching, skis and Boss seat. Any ideas on best sled to buy would be very helpful.
