Analog Speedometers are notoriously inconsistent and not always accurate at high speeds. For you it reads 112, for someone else it reads 106. I believe the factory rates the limit at 110mph, so it isn't that you have a faster car than the guy who's governor kicks in at 106. His speedometer error was 4mph under while yours was 2mph over. Neither number is all that bad when you consider how many variables there are that affect your actual speed. Consider whether the tires on your car are over/under inflated, how worn down they are, etc. You can't expect the numbers to be equal from car to car and year to year. My old 95 SE with firestone firehawk tires showed about 116 before the governor kicked in.
