Aside from the normal stuff (LOL), if the car is running coils then they need to be up to stuff. Then there is adjusting the bands for the transmission as needed and different steering then A's. Mostly it is just ,maintenance, grease oil etc. That and remembering you only have a transmission brake unless equipped with aftermarket outside brakes, along with remembering just because you can lock the brakes up does not mean you are stopping, so plan ahead. Once you learn to use the the three pedals and hand throttle/spark, driving is not bad.
If and when you get one, get the repair manuals along with owners manual, tells just about everything you need to know, to fix or drive.
