After winning an auction, usually it is the buyer’s responsibility to load the machine from the seller’s place and haul it back to the buyer’s shop (transportation). Sometimes, the seller is even located in another city. For example, I have transported a Powermatic 66 tablesaw from San Antonio which is a 3-hour drive (one way).
It would be convenient to use a truck for this purpose; if not, you can rent a U-Hall trailer (with a ramp), and in this case your vehicle obviously must be able to haul the trailer. If you are lucky, the folks at the seller’s place have a means to help load the machine into the trailer (for example, use a forklift). If this is not an option, you still could dissemble the machine into manageable pieces and load the parts into the trailer. Remember that those vintage machines could weight 300-500lb
After loading it, the machine has to be secured in the trailer or truck bed; the easiest way I found is to use ratchet tie-downs. Those sold by Harbor Freight are actually pretty good for the price (disclaimer: I am not affiliated with Harbor Freight by any means, except being a customer with them).
Here is a picture of my PM 66 tablesaw tied down to a trailer:

After arriving my garage, to unload the machine from the trailer, I used a hand truck. I first remove the parts that can be easily taken off, for example, tablesaw top, jointer fence, etc… then tilting the machine body against the hand truck. All the transportation and unloading were done by myself alone.
