There's a few with the BSR at Mendip now, cars is solid as a rock, and is basically a road going Team C buggy so no problem with spares at all. Springs are a little on the hard side but Hobo springs are softer and fit ok ..
Most have gone for the Hyper GT .. which is a rolling chassis and needs electrics but they're cheap and the car is a good performer.
Best price is from John at RC Octane, Mendips local shop -

He doesn't have them listed on the website yet, but they're going for £175 as a roller .. give him a call !!!
