From posts on here Tom, it seems most Kymco parts and certainly the consumables are readily available in the USA, especially if you’re comfortable ordering on line. Specialist bits like body panels might take a while though? Further afield eg Europe, Philippines etc., Kymco stuff also readily available and many will ship to the US.
If you see a Kymco you like, I’d say go for it. Mine has been very reliable so far at three years in!
