    Thinking about moving to Colorado, maybe the springs area. Coming from Kansas there are no emissions laws.On the emissions testing end of it, do diesel pickups have to be tested? Any testing required on older cars? What about modifications done to vehicles? Is it a tail pipe test only or do they visually check to make sure things like egr's, egr coolers, and converters are still in place on diesel pickups? Thanks
