i can see you spending what little money you have on some parts and trying to build a car and then finding out that it doesnt fit together. you just got into this hobby 2 weeks ago. you need to calm down and figure out how to separate your ideas from your dreams. if your going to try to build a car piece by piece for cheaper than buying one then your in for a wake up call. people buy new cars and part them out on ebay (selling each individual part ) and make decent profits because the total of each part is much more than the whole car.

you have a stadium truck and want something that can go more extreme off road. get a truggy or a monster truck. you said you have limited $$ so i would recommend the Cen MT2 or the Magnum (almost same thing)

as far as getting a building experiance, you need to get a kit. then from that you can customize it by buying parts or making your own. for a monster truck kit i must say that the only one that i know of is the savage SS.

how old are you?
