Thanks man.
So far the only semi-serious maintenance I’ve done is changing the oil and oil filter. I worked on little things like getting the armrest to stay put and getting the garage above freezing. Sometime soon we’re going to take the car to a mechanic (my dad knows a guy who restores Z’s) and have him look everything over and then go from there. My dad drove it today and had no complaints, so I guess that’s a good sign.
