This afternoon my girlfriend, her dad and I drove about 100 miles to a family member's house and my girlfriend's dad bought a 1960 AMC Rambler 4-door with 37,000 original miles on it. It has always been in a garage and is almost immaculate. The car does not currently run and will likely need a complete brake job to make sure it's safe. How widely available are parts for that model year AMC vs. say a GM or Ford product? I don't remember the last time I saw an AMC, especially that old.
Thanks, I am familiar with those cars! 😎
What model Rambler is it? Engine? Transmission? Engine could be anything from a flathead inline six of prewar design to a 327 V8, depending on the model. For 1960 it would be an American, Rambler Six, or Ambassador. Transmission would be three-on-the-tree, with or without overdrive, or a 3-speed Borg-Warner automatic. You should consider purchasing a factory shop manual (reprints are available), or at least a Chilton or Motor's manual covering the car.
Parts are generally available but can involve some searching as you might expect. There are some things that are no longer available that require some resourcefulness to work around. I would recommend checking in on an an AMC-specific online forum and joining an AMC club.

There are some online parts sources specializing in AMC vehicles, here are a few to get you started:

It's got the straight 6 engine, the valve cover was off, and I was astonished that only 2 bolts hold it in place. The cam and rockers were in great shape and oiled. The transmission was an automatic. I found it interesting that the gear selectors are a series of buttons on the far left of the dash, where a vent would be, nowadays. Top left button was N-Start, then Reverse on the top right, and 2, 1, L on the 2nd row. Does that tell you anything?
I believe that would be the "Rambler Six" model that was renamed the "Classic" the following year (1961). It has an overhead-valve inline six displacing 195.6 cubic inches that is based on the old flathead. If you look on the passenger side of the engine you will see there are bolt-on covers that on the flathead you would take off to adjust the valves. The engine may or may not have an oil filter, that was an option. The oil filter would be a partial-flow type that spins onto a mounting plate bolted to the front of the engine and has external oil lines. (The following year a die-cast aluminum version of that engine was introduced.) This site has lots of details on that engine:

The engine has mechanical valve lifters that need periodic adjustment that is done with the engine running at operating temperature.
The pushbutton control for the transmission was a popular thing at the time that was first introduced by Chrysler in 1956. On the Rambler's controls "1" and "2" refer to two drive ranges. Drive "2" starts out in second gear which was supposed to help prevent tires from breaking loose on slippery surfaces. ("L" holds either 1st or 2nd gear, depending on speed.)
A torque-tube driveline (enclosed driveshaft) with coil springs in the rear is used. Front suspension uses trunnions, not ball joints, that need regular greasing to prevent excessive wear.
