overkill
Thats a reasonable prices but all the listed equipment comes in the kit except the tires.
to this you need a rear exhaust engine, pipe, header and 2 hi torque servos as well as a receiver and battery and most starter boxes aren't strong enough to turn over a new (tight) 21 size engine.
the mbx-5 is a high performance buggy and unless you are right at the top of competition it would be overkill. the sacker is an excellent car(its a ripoff of the kanai3 and some hop ups fit).
the money spent on the top line car would be better spent on a motor, tyres( buggies destroy tyres very quickly) and electrics.
hope this helps
