I never got into the Hot Wheels track much. I preferred pushing the cars around in various scenarios I made up. Also liked to display the cars. Same with Matchbox cars and trucks. Had some police, fire and ambulance vehicles. Used to recreate some of the things I saw in my neighborhood growing up.
Matchbox cars were more realistic and had more vehicle choices. My brother was a couple of years older and had a some of them before switching over into Hot Wheels but he was getting a little old when they came out.
Thanks for the pictures.
