Good price for this 1973 Convertible?

Hi everyone, im eyeing this 1973 Mustang Convertible going for 16k. It looks to be well taken care of, and owner has records and receipts going back to the first owner. It has a 302 engine, 3 speed manual, and 55k miles. Owner says its mostly all original. A few things im concerned about:

• he says theres no rust, but it looks a bit painted on the bottom. Can any eagle eyed car experts weigh in?
• it has no power steering or AC. I dont think i mind no AC, but no power steering is a bit worrying. How difficult will it be to drive? Ive only driven cars with power steering before.

Overall, does this seem like a good deal? I will also have to drive it back home about 330 miles.
