Hey guys! I've been looking for a new car (tired of constantly having to repair my outdated and discontinued 1/18 Ruckus) and a Granite MEGA recently became available at my hobby store. I know the guy, very trustworthy. He said it was a stock Granite MEGA with only about 40 hours of runtime on it. I looked it over and everything seems to be in working condition. He even let me test drive it on the carpet track while we were there. He's selling it for $175. My question is: are all (recent) Granite MEGA parts compatible, if I need to repair something, or want to upgrade? (Or if it gets discontinued) Thanks!
