1/8 scale nitro buggy, its the top class & very popular just about everywhere around the world.
As for a buggy, people will tell you what they like but best to do some research, just because something is more popular doesn't mean its the best for you, & alot of racers are just fan boys & follow a top driver, if he changes then so do they.
Also look into customer service & what sort of help you can get when it comes to set ups & racing advice.
On that note, just save yourself the hassles & get a JQ Racing Black Edition, great buggy & customer service thats hard to beat, you get info straight from the cars designer & owner of the company & a family of team drivers. The car is really good.
