My favorite car was a '67 Chev El Camino. I had it in the late '70's. Can shoot myself today for ever selling it. It was a performance car. The motor was pulled and built. I removed the Powerglide 2-speed automatic and installed a Borg-Warner 4-Speed manual transmission. The 10-Bolt differential was pulled and a Chrysler 8-3/4 installed. I could switch out the carrier to change gear ratios. That offered ability for going on cruises vs. at the track.
Paint was a sky blue with matching stock interior. Factory A/C made it a nice ride. A pioneer sounds system was installed in the dash nicely. I had a removable top for the back. For trips that was awesome. There was a foam pad and covering, so I could sleep in the back. Made for trips to the desert and the mountains comfortable and giving a gypsy kinda' feeling for looking about.
