The reason I bought a MatRat from JE was purely because DCM told me the car was made from different plastic to that of the XPro version, which he stated to be very stiff. I wanted to see for myself and possibly show it alongside for a comparison in the review.
I also know that many people beleive a bendy (to a point) car is better / easier to drive than a stiffer one. A great looking chassis but with softer materials - it'll be interesting to see how it goes.
