Im getting my spark in a few days so i decided to read alot of the older posts to get a full understanding of the good and bad. biggest complaint seems to be the traction control is very aggressive. when its on the wheels spin and cuts your power when tyring to gun it to merge in traffic. whats the cons if any to taking the traction control off. it doesnt rain much in vegas so i would only have the traction control on the 7 times a year it does rain.
