Interesting article about the lone SD Grand Am. I like the license plate on the front of the car I got this one from one of the drivers for Road Test Magazine when he sold me his entire collection of Road Test Magazines. It's actually just cardboard which made it easy to bend as you can see on the Pontiac Grand Am. Mine still has tape on it that was used to stick it on test cars.
Another rare '73 Grand Am for sale in Pittsburgh. I like it. https://pittsburgh.craigslist.org/cto/d/pittsburgh-1973-pontiac-grand-am-door/7612262573.html
