Questions to ask when purchasing '73 mustang Mach-1?

Hi again,
I've been thinking on whether i should purchase the '73 Mach-1 and I've
decided I really want to. I know I don't know much about cars, but I want to
learn and I think a 'cool' car like this is the best way. I also want to
maintain it on my own.

I've been working on a list of what I should ask the owner about the car.
What other questions would you ask a seller when buying a Classic Mustang?
Assume that this car isn't being purchased for restoration; it'll be used as
soon as it leaves the lot. For those who haven't seen the previous posts,
it's a '73 Mustang Mach-1 with automatic transmission.

This is what I have so far:
1)vin Number?
2)Door tag number?
3)How many owners?
4)What engine does it have?
5)What parts have been changed?
6)Has it been in an accident?
7)Has the car been repainted?
8)Condition of the dash?
9)Condition of the seats?
10)Where does it have rust? **Should I ask for specifics? Example, is there
rust on the doors?
11)Any problems with automatic transmission (ie. delayed engagement, fluid
level low)?
12)Any problems with engine? Is engine oil clean? Are there any leaks? Is
smoke coming out of the exhaust? Any awkward noises?
13)Does A/C work? Owner said that it worked but it needed gas.

The good news is that I went to one town when I checked it on Saturday, and
when I called yesterday, the owner was at another town (about 50+ miles
away). So I can only assume that the car's been driven at least 50 miles.

Are there any other questions I should ask the owner that are specific to
this year's Mustang?

Thanks again.
