when we first started to search the cruzes we drove the eco for a weekend and we liked the dic showing the 25 50 and 500 mile avg readings. but we wound up with the ltz/rs model and when flipping through the dic pages one page is blank. might be that avg page is not there and not available in the ltz. if not how hard is it to have it put in programmed into the dic. it must be available if the eco has it the same computers in the same car correct? anyone have an idea? thanks
