I put power. Because that's what i want changed the most. But realistically, that's not going to change much as i don't plan any mods in that area. Just an intake.
My priority is looks and handling. And they pretty much go hand and hand since i like a stockish look. Like rims, they are for looks but also are a necissity for good tires. Springs, handling and drop, etc. My car looks decent, and handles decent, i plan to go further with both.
I'm actually fairly content with my stereo but that always gets upgraded little by little, not a priority at all. I think this is one of the best places to spend money though as it will go from car to car. I actually haven't put any money into my accord system wise, i just took what i had out of my last car.
