Given then info you provided, ITS A FREAKIN' STEAL!!!!!
How good a friend is this, as he may resent you taking advantage of him one day. [:D]
The REAL question here is -
Will you be the end user??
If not, BUY IT, sell it, and buy more guns!!!! (your sig line not withstanding)
If you will be the end user, consider: (I used to own a BLaster)
I wouldn't recommend one for anyone over 190 lbs.
They got enuf power, its just a size thing. YOu'll be pretty cramped if your more than 190, or taller than 5'10"
They have a short wheelbase. That means they wheelie easily. That can be a bad thing, or a good thing. My Blater died when I put a twist throttle on it, and tried to wheelie over a log. I rolled back the throttle wide open, and couldn't get off it.
I center punched a VERY stout tree wide open in second (maybe third) gear, and bent the frame. Went over the hadlebars, etc etc etc.
Now, given teh above, the Blaster is STILL a great ATV. PLENTY of power (for teh right rider)
Check to see if it has rear disc (or rear drum brakes) If rear disc, GET IT.
Then sell it, or use it yourself, depending on the ^.
