if you want a car for bashing i would go for a monster truck they are the strongest but i think the strongest car for good money i would say the hpi savage ss or 25 they are the best one but the savage ss is a kit do you mind a kit
i think that is the best car for you or you can move on to traxxas they do good monster trucks go on this website....
www.traxxas.com there are good trucks there
