When comparing the cost of the kit its important to factor in the additional items you will need to complete the car.
With all the X-Ray cars I have had have been ready to go out of the box.
The TC5 I had provided good value in terms of performance but material quality and fit was extremely poor.
I was already to get a cyclone but after adding up all the little extra(I was told were required) parts the total cost was close to that of the x-ray.
I now have the top car and so far its looking to be on par with x-ray in terms of fit, material quality and durability.
