Sounds promising, but I second Ernie's suggestion to ask for a description of the maintenance history. If he's the original owner (which you should find out about), the fact that he got it to 2,400 miles should mean that he's kept the valves and chains in adjustment, regularly replaced the oils, probably retorqued the head bolts at least once, and probably adjusted the timing as well. Also, if it's a 2004 with only 2,400 miles, that means it probably sat still for long periods, so you might check to see that the wheels are not out of true or out of round.
And definitely test ride it or, if you don't have your license, have your friend do it. Check for excessive vibration, pulsing from the brakes, pulsing from the wheels during curves, proper idle and power, etc.
I'm from the northeast as well, so I would want to know how he stored it for our long wet Winters. By your account, the outward appearance has been maintained. But, for example, did he take care to fog the motor?
