The last car that I really got involved with body wise was a 78 Trans am. (WS6 Y88) I had to remove the bumper of my 05 CTS and noticed that the general design hasn't evolved much. Fasteners and materials are a lot different but it's mostly put together the same way. Just a plastic nose cone over a beam type bumper.
Thank god engines have evolved. Well, at least fuel management. I'm still rockin' push rods
Anyone remember working on Q-jets?
