Something that's nice on all old 4WD Toyota models is the clutch start cancel button, which is nice for when you need to start your truck and put stuff in it or when you need to clean the windows off and don't have to crawl into it to press the clutch in to start it.

The altimeter in the Land Cruisers and 4Runners is also cool

And in the MK2 Supras and MK3 Celicas you could get seats which had a hand pump on the side which filled an air bladder to adjust lumbar support. There's three buttons on the left side of the seat to bleed the air out. I've had a lot of people who asked about my Supra ask me if it has the air pump seats since they used to have a Celica/Supra and they loved the seats.

Another thing I like on my Supra but can't find any photos, but there's a prop rod for the spare tire cover so you don't have to hold it up when removing it or checking the air.
