Drive 1000 mile bringing new old car back home

I sold my "Spirit of '76" Dart Sport a few years ago to a guy from Canada.
He flew in & drove it back. The car had 88k on it.
I had driven it from Tulsa to St. Louis & back before he bought it. No problems.
He picked it up & drove it to Canada, no problems. It used a 1/2 qt of oil in the whole trip.
The only thing was, they don't build cars like they did these. I think we are so spoiled to even the basic comforts of modern cars. Things like A/C, reclining seats, & cruise control.
I had a new sound system in it, but couldn't hear it, due to the windows being down in 80 degree temps. The seats will wear on you & I sure missed the cruise control. I would be anywhere from 50mph to 80mph.
The car was a 225 with 4-speed OD & averaged 32mpg on that trip.
It was fun to show my son what cars used to be like though.
