RE: should i get this buggy
There's nothing much wrong with it, but it's a cheap buggy. IF you gte good and love the sport, you will want something better very soon. You don't really have enough money yet to get a 'good' buggy. Save 600 and get a Hyper PBS or comparable $430+ RTR buggy, two 7.2v starter box batteries, a charger and a decent steering servo, you'll be ready to race the following weekend. I know this buggy was new, but something to remember; buying second hand is risky and buying from ebay is risky. Buying second hand from ebay is plain crazy (although you may get away with it once or twice as I have, but I have also been stung BADLY twice).
Of course, if you have radio and engine already or the 450 is budget for buggy only, you have a pretty wide choice.
