I'd say this a good buggy.
But it depends on what you're going to do w\ it. If you're going to race it every once in a while, the Lightning Pro 2 is probably the car of choice. If you're only going to bash, the RR is the better buy.
Travis Amezcua, Brian Kinwald, & Atsushi Hara all race the Hot Bodies car. Amezcua has said before that he didn't have to do much maintenance on it to get it running quickly. Shows enough about RTRs if you ask me.
This is also very similar to Kyosho's older car, the K3. I've heard rumors that some of the parts from Kyosho fit on it, so if that's true, that's a lot less of hassle getting parts, seeing as I don't think too many hobby stores sell a variety of Hot Bodies parts.
Overall, its a good choice. Good luck.
