Depending when your "Time" was, we got Spoiled with the pre-smog days when pollution control was the addition of a PCV valve, and when the Smog stuff came on the cars, air pumps, Vapor cannisters, TCS etc, it just wasn't the same.......Then the Insurance Issues,and finally the Gas Crunch.........Nowdays it seems that the Pollution stuff is worth it's weight in Gold.......My $.02
