Just got back from running a few errands. I'm still on a mission to get the GF on two wheels, especially since she has her endorsement and passed the safety class. So we hit up the local Yamaha dealer and sit her on a Vino 125, C3 and a Vino classic.
The Vino 125 is a bit too tall for her. She can't flat-foot it, but the seat has a lot of foam in it. I wager if we shave off 3/4" or so all around, it'd be ok for her. It's nice because it's inexpensive, has a front disc brake and an acceptable amount of power. The power is important because we live on a hill and there's no way to get up to our place without a steep road or two. So the Vino 125 is acceptable, once the seat gets some foam knocked out.
The C3 wasn't bad. The GF thought the looks were acceptable. It's less expensive than the Vino 125, but at 50CCs it doesn't have the required amount of pep to get up the hills around here.
The Vino classic was the same deal as the C3. Decent enough scooter, not enough power.
Moving on to the Tank dealership, I'm impressed by the low prices. Now, I had done some research on these online and everyone says they are cheap Chinese junk knockoffs of Honda designs. I suppose they must skimp on things some places. It appears they skimped everywhere, though, except the "oh, wow" factor. Their cheapest scooter had a remote start and remote kill!
So we have the salesman pull a model down off its centerstand so my GF can hop on and see if it fits her. As he does so, one of the bolts holding the centerstand on to the scooter
falls off. 
My buddy and I are on the side where the bolt fell off, the salesman and the GF were on the other side. Yeah, we let her play with that model for a bit then we got out of there. No thanks, that's some serious Chinese junk.
Next up was the Honda dealer. They have an Elite 80 which might provide enough punch for the hills around here, but it's still a maybe and it's still too bloody tall for her to handle. So that's out.
Honda's Helix 250 is out due to price. It's over twice as expensive as all the other models we were looking at today. Honda's other offerings are either too small of an engine or too high of a seat height.
She also can't fit on a Rebel due to the plastic covers on the sides and finds the Shadow VLX is too heavy for her, despite a very low CG and seat height.
Well, the quest continues. We think the best idea is still a used Vino 125 with some seat shaving.
