Drive it those are good choices I owned an 04 kodiak 450 (the wife's former ride)the only thing I didn't like was that it has a very stiff ride and it was geared to low. It had gob's of power but it would wind out with to much power left on the table, top end wise because it was maxed out gearing wise. I also had an 04 grizzly as dose my father his got so hot on a trip to the mountains in colorado that the gas was boiling in the tank. They were both cold blooded and had to be babied when cold starting for longer than I care to wait for a machine to come to life. Other than that they are awesome quads. Those grizzlies are what made me deside to go to fuel injection. So I brought a king quad it was great but the silly little racks were a joke . Then I sold that an picked up a sportsman 500 efi an am very pleased so far. I think the grizzly will be a fuel injection 700 soon.Maybe you want to wait ? Just my to cents
