No Jim, I haven’t. But like auto extended warranties you’ll probably never use it, and a quality scooter is much simpler than cars. The battery is the only single item on one that could be costly and if you take proper care of it, be it acid or lithium ion, they last a VERY long time. I just upgraded my scoot after riding it for 8 years and lithium battery was still going strong. I bought from Super Bicycles and Scooters in Myrtle Beach, S.C. Great outfit. Been there with the same owner/team for long time. Suggest you check out their website. I can vouch these folks stand behind their scooters.
