If it's a '76 the odometer will be in miles as '77 was the first year for kilo's.My brother had a '76 Tuxedo Black 455 4spd w/ 34k mi on it.He was third owner.It was pretty well loaded except T-tops and tilt.Even had the power lock switch on the dash beside the defrost switch.Last year for that location.I once had a very low mileage '76 Grand Prix w/ 76k mi when I bought it in the late '80's.Cool riding car.It was loaded w/ the 455.
