#1 get a 2007 b/c it will less problems the reason behind this is that it is proven that 1st year redidesigns always have more problems then the later model#2 forget the dx it has nothing its a car to get you from point a to b#3consider the lx or ex only consider the si if you are willing to pay more and not get as good mpg#4 the lx would have air conditioning power window/doorlocks am/fm with cd radio #5 the only advantage to the ex is that it has steering wheel mounted audio controls, alloy wheels and a sunroof good luck
