I have a few tapes from Ford from like '91 and '92 cuz my dad used to be a body shop manager for a Ford dealership back in the day. I personally think the whole idea was awesome for Ford to do, I mean, give a tape (or cd, if you have a newer vehicle) to the buyer so they can hear how good the factory stereo sounds!
Are those tapes worth anything now? I have a couple somewhere that are still in shrinkwrap!!
