Hey, i have a '99 and ive noticed this for a while. when i drive, say for instance, 30 mph, my speedometer reads '40 mph'. or if im driving 65 mph, it reads 75 mph. ive learned to adjust to this while im driving, but i drive a standard transmission, and im afraid it will screw me up with other manuals when i drive later on in the future, cause im only 17, so i have 50+ years ahead of me driving. anyone know why it is showing up like this?
