I have been searching since august for this bad boy and I finally found one. Unfortunately I will have to part with my 02 40th anniversary gtp. A few noob questions. How good is the gas mileage? I've seen it written down but those are only estimations. The only thing wrong with this gxp is that the HUD isn't working. I turn the knob press the arrows and page button and nothing happens. so what gives? Any input greatly appreciated.
