Unless you are on the Nemo racing Team parts can be expensive and hard to find for the Agama. Usually it is not a big deal, but if something goes out of stock your stuck waiting because no else really sells the parts besides Fierce rc. Like the clear stock body is $41.63 on the Nemo racing site plus shipping. Used to have the a319 and car drive good, but finding parts was difficult at times depending on what you needed. As for the Mp10 have not drove but parts are everywhere and lots of aftermarket.
