Speaking of custom license plates. The other day I saw a car that had a plate that read "read2um" I figured she must have been a teacher.
Also if you plan on getting your Caliber's windows tinted I would recommend 20% or 30% all around. You might or might not want to tint your driver and front passenger windows, depending on what you prefer.
I got my Accord tinted with 5% tint on the rear passengers and back windows. Although it looks really nice and cool, its hard to see out of them, especially when its dark.
