My advice is to buy something that a local store stocks parts for, even if you buy the actual kit online (although you should really support local hobby shops - its a niche hobby overall, and they deserve your support).
R/C cars break, and you really want to be able to get replacement parts in a timely fashion. It's heartbreaking to be out of commision your first hour of fun on a weekend with no recourse for repair until next week when a part arrives.
You should also keep track of what you break, and get used to buying the replacement part in pairs, trust me
