my vote is build 1 for the daughter and 1 for you with a 125-150cc lifan or piranha engine. I have had good luck using paint stripper gel to get paint off plastics, without hurting the plastic. but you have to keep an eye on it. as soon as the paint starts to blister get it off there. a soft plastic bondo (body filler) spreader helps with removal. they probably got painted for a reason, so they probably wont be nice underneath, but you can repaint with the proper stuff. Any type of abrasive pad or scraping will for sure damage the plastic. but you might find they need sanded and painted anyway.
