Welcome Kymco Owners!
I have two Buddies. A Buddy 125 and a 170i. They are absolutely fantastic scoots. My wife and I took our Buddies to Michigan this past week and logged about 450 miles on them riding around the Upper Peninsula. You can't go wrong with a well maintained Buddy.
The Buddy handles like a dream. My Buddy 125 tops out at about 55 mph on straightaways and my wife's 170i tops out at about 60 mph. I also have a People 250 with large wheels and I really don't notice much of a difference in handling between the two. I bought both of my Buddies off CL with less than 100 miles on them. I saved about a 1/3 - 2/3 off the price of new ones. If you can find a clean, low mileage one, go for it. You can't go wrong.
I agree, 14,000 miles is a bit high, but it all comes down to how it was maintained. If the bike is super clean, for $1,250, I don't think you can go wrong.
One of the perks of owning two Buddies is that they both fit comfortably in the bed of my 2015 Chevy Colorado. Last year, we could not get both of our Like 200's in the bed of the truck. We had to put one of them on our Versahauler.
