Anyone have any experience with the IMX (IMEX) brand 1/10 scale vehicles? I found a couple of their vehicles local cheap, but, even though i know they initially started in N.Y. and then moved to FL. I have no actual experience with them. I can get them cheap, so, if they are worth it, I'm looking to pick them up as starter vehicles for a 9 and a 10 year old. Some of the questions i have are, are they fairly durable, or do they break easy? Are parts easy to get from IMEX, or is it a customer service nightmare? Anyone ever upgrade them to run BL? Any known out of the box or first runs issues? Anything i am forgetting that i should know about them?
