I have plopped-down a deposit on a Taiwanese-made, '06 Agility 50, 7,800 km. The concern is that the engine oil has not been changed for nearly 4,000 kilometers and I am wondering if I should reconsider buying the scoot. Any thoughts on this? The only modifications to the scoot that I'm aware of is that it has only been deretricted. Let me know what you all think. Josh and Donald. chime-in if you can. Thanks for your help.
