Yeah, the EVIC will translate the mileage, etc, but not the actual speed. That said, I don't even have an EVIC, literally the only options my car has is a Power Drivers Seat and a "Smoker's Package" which to my understanding is just an ash tray. Regardless, I'm throwing the black Concorde faces on my gauge cluster when I get it. (As well as an OTIS.)
I just hit 33k on it today though, so since I've got a lot of time yet to spend in this car, I figure I might as well make it as good as I can to drive.
