I rode it home, then went straight to the Department of Licensee to take care of the title/registration business. I pulled off the rear basket and then took off for an hour or so of scooting around town!
It's really important to me that I thank everyone that's been so helpful with their thoughts and advice as I've been considering my options. You're all fantastic and I can't see myself ending up with this scoot without your input.
Anyway, the Blackjack itself seems to be in pretty good shape. It's never been downed, and the paint's all clean, less the usual you'd expect from use... the only defect I've noted was that one of the round red reflectors attached to the license plate bracket seems to be missing (I'd assume these can be picked up for cheap). I guess the ad that I was looking at was old, as the scooter had ~400 more miles than was listed (meaning it had 2000 and not 1600 on it), but that was hardly made me reconsider. The previous owners took good care of it, too - with the first maintenance done by dealers.
Anyway, all said and done, I spent under 2200 bucks for the scooter and the registration/title/tax/etc. It may not be a brand new shiny 170i, but my bank account is in less pain than it would have been if I went for a brand new Buddy.
It all looks pretty stock Blackjack, but I took a couple pictures for kicks


You can see the spot where the missing reflector ought to be in this one (next to the blacked-out plate).

So yeah! Thanks again everybody - you're all the best!!!
