So my parents gave me their grey-ish 2007 Toyota Corolla CE and I was wondering if anyone had any idea as to how to mod it and make it look it nicer? Eg sound system, lights, deck, etc. I'm trying not to spend too much money on it, but if anyone has any ideas as to what can be done to it along with company names so I know what to look for when I go to buy stuff. I was thinking about putting in those bright white/blue lights (not sure what they are called - if anyone can help me with that? And also a new sound system (sub/amp/speakers) and also a new deck (contemplating whether to get a built in GPS in the deck or just a portable one?). Any suggestions are helpful, thanks all.
