The chassis codes are used sparingly for GM and Ford's North American cars, with most being referred to as letter-body (GM) or insert-big-cat-name-platform. Those aren't of too much use, as they usually don't indicate generations too precisely.
But, if you dig deeper, you can discover GM and Ford have another tier of chassis/development/production codes which identify vehicles better. Feeding one of those into Google usually reveals "technical" articles with many of those mentioned.

Thus, for example, the DEW98 Ford Thunderbird (the most recent, retro-inspired generation) is [M205], and the Saturn L-Series is [GM2902] (a platform shared with the Saab 9-5).
