David,
Do you remember what you paid for your Maverick back then?
I know what you mean about feeling old, I bought my '71 Mach in the spring of '72. It was a demo with 5,000 miles on it for $2,995. Still have it, now with about 40,000 miles on it.
I did see a tee shirt a while back that seems to fit nicely regarding feeling a bit old. It stated, Inside this body is an 18 year old kid screaming, "What the hell happened".
