I think I would hold out for an 09. A lot of improvements, including the electronic reverse, new track and lighter weight. I have not heard good things about the older M8s, so I am hesitant to buy one.
I'm in the market for a new M8 or Dragon 8. Tough decision.
I came off an 06 M7 which I loved, but could use some more power.
FYI, if you do want an 08 M8, there are left over 08s for $7700-7800 on ebay.
I really liked my 162 M7. I would go 162 again, but not sure if would go 155 or 163 on the Dragon.
I like the handling of the M-chassis better, but like the extra power the Polaris has.
Snowtech has dyno tuning the 800 Dragon this month. 154 hp is what it made stock.
M8 is supposively 145ish?
