If you like it and you can afford it then buy it
It got 1st 2nd and 3rd at the world championships so there is nothing wrong with the chassis or its durability.
Mikes information is accurate - there isnt much more to add other than you need to use some small grub screws in the front wishbones to prevent the hinge pins from dropping through and fouling the chassis.
What other information are you after ? A car is only ever as good as the person who controls it which makes the all too often questions of "which is best" etc a little frustrating.
