D4WCE spareparts

[Kiixx]

As the D4WCE is discontinued, but i have come across the option to buy one brand new in box for about £ 140-150, so i now have some questions.

Spares, can most if not all parts of the Associated B44 be fittet to the D4 as spares ?

And Wheels, i have a lot of pre glued wheels, bothe front and rear that are unused for my XX-4WE can they be used for the D4WCE too ?

And last is it worth buying, the B44 cost about £ 200 new in box.
