Hpi is a great company if your looking to bash they do not make really competitive race cars (except for the pro 4). If your going to bash and barely ever race I would get the rs4nmt2 or the ss you will have much more fun with 4wd and it will handle much better. I have the original nmt and its a blast and it has an O.S. 18cvr in it. I also have a gt and its fun too but you can only do so much as traction is limited so the rear likes to kick out. you also go through spur gears because the chassis flexes in the back.
