ok not trying to be a smart ellic here but if there running 2wd buggy why are you asking about a 4wd buggy? if thats not one of the classes that you listed. the B44 is a great 4wd buggy. also are there gonna be parts avalible at the track ? if so what all brands are they gonna stock parts for is something to look at also. so that in making your choice of which vehicles to buy or running classes
