1970 vs 1971 Z28 (apples to oranges?)

[markjohnson]

Another factor to deal with is that here in St. Louis, cars 1971 and newer need to be smog tested. '70 and earlier are exempt. This has influenced my buying decisions on several cars. I don't want the hassle of historic plates with a mileage log book and can't handle the sight of an 18 year old stranger driving my car into the bay at one of our local smog inspection stations. Dodged that bullet for a long time with my 540 CID '79 Malibu until I decided to stick with cars '70 and older as long as I'm living in St. Louis.
