either a Downtown or a GT in the 300cc class, hands down!.
New, left over, or clean used.
IMHO, you will be happier in the long run.
These are dream machines that are easy to maintain, good gas mileage, and plenty of power.
Concerning modern motor scooters, 250cc - 350cc is the sweet spot.
If I was in the market for a scooter and came across a nice clean 250 at a good price, I would give it a hard look and a test ride.
Good luck in your search.
ps: It is always desirable to have an honest dealer within reasonable distance of your home when buying a motorcycle or motor scooter.
