Yeah Jamie's right, you will struggle to find anywhere to race a 1/10 nitro buggy. Also it won't be strong enough and you'll struggle to get spares. Even if the shop you get it from says they stock it, the question is for how long? if it doesn't sell well (which it probably wont') they will drop it and you'll be left with a shelf filler.
The hyper 7 is readily available has tons of spares and can be got little used for under £150 on ebay. it can also be upgraded to a respectable pro level buggy and just will not break (well mine rarely did)
