It sounds to me like your wanting something incredibly cheap, with the looks you want.
Honestly, you will be more frustrated than a 16 year old boy with a girlfriend that wont put out if you buy that New Bright. They are fine for children. Children only. They dont go fast enough to break, they do not have any suspension at all. (as in, their axles are solidly mounted to the chassis and have no movement). Their motors are weak and can barely propel the vehicle on flat ground, and they eat batteries like there is no tommorow.
about the only mods you could possibly do to one would be to upgrade the motor. Which would be pointless because they dont provide enough power to make it any faster. Nothing from a hobby grade RC vehicle of any kind is gong to fit, or work on it without alot of modifications. Even the wheels and tires are completely diffrent than what hobby grade vehicles use. Sure, you could buy one and completely tear it down, mod the hell out of it and make it into something, but it would be like trying to turn a completely bone stock dodge avenger into a full blown tuber rock crawler. Sure, it can be done, but at what cost.
You will come out far cheaper to just buy a cheap hobby grade rig and work your way to what you want from that angle. I have seen just about any scale body imaginable on a real hobby grade rig.
However, if your just wanting something cheap and fun, that is also upgradeable, then I would go with the almost ready to run duratraxx cliff climber, or the ready to run version
