Hoo boy - you asked THE question!
Seriously --- I think you are in great shape!
Why, because I don't think you can go wrong with either of the two scooters you've settled on!
I think a month, or a year, after you buy either of these two scooters you will be happy with your choice!
I've read the reviews for the Buddy 170i - surely you've investigated both scooters - so you are hearing good things about both of them.
My choice of the Kymco was easy in some respects, because the Kymco dealer is nearby, and the Buddy dealer is not.
Perhaps it will come down to which dealer you would be most comfortable with, if it is the same dealer for both scoots -that decision was made simple for you!
Which scooter has the best servicing fees for standard maintenance (Valve adjustments, oil changes, etc.) : or the best prices on the things that most quickly wear out on a scooter, or parts availability ? (though I've never heard of a problem with getting Buddy parts, and I find it easy to get parts for my Kymco - not that I've needed any - just stocking up on things for the future)
Anyway, I'm very happy with my Kymco LIKE 200i LX - but I'm also pretty sure I'd be just as happy with a Genuine Buddy 170i (love that fuel injection on my LIKE,too!)
You really have picked 2 very good scooters! You'll be a happy person as soon as you own and start riding either one!!
See picture of a happy Kymco 200i LX owner, at sunrise. (can't sleep-in when you have a scooter! Sorry for the attire, yes that's my jammy shirt. In a hurry to get on my scooter..... Most scooter riders are better dressers than this!)
Either way - please report back and tell us what you decided - and then give us an owner's report after you get some miles on it!
