Get the serpent 747, but most of all visit your track to see what people run here so people can help you out if you need help. Personally I believe world champ titles don't really matter, as it won't make you a world champion. Any car that makes it to the Worlds should be a car worth buying in my opinion. Serpent has been in the industry for a very long time as far as I know. Yes, they are made in China now as thry use to be made in Netherlands, but the quality is still top notch in my opinion. I've has a few crashes with my 733 and nothing broke. My body just got dented. Parts are readily available is most popular shops as well as lhs's I believe, it really depends on your location. My local club runs X-ray, but i decided to run serpent as I believed that their time in the industry would back them up.
