My son (B-Max4II std) and me (B-Max2; old B-Max4 roller for spares) are really happy with our Yokes. Getting parts may be not as easy to get e.g. as for AE cars, but on the other hand you don't really
need many spares. Prices in Japan or France are really reasonable, only shipping is more expensive. Parts support in Germany is slowly but surely getting better also. I'll probably get a B-Max4II Worlds Spec next year (or whatever version will be available then) although there are many interesting 4WDs on the horizon. I just cannot imagine a better handling car.
