Pegleg, Your money, your decision if you decide to adopt a car looking for a new home. Up to your wife to decide if you get to sleep in the house or the garage!
The biggest thing that would concern me would be engine and parts availability on a car nearly 60 years old in your area. I've had many conversations with Fabrice and see what he has to go through on simple things such as nuts, bolts, hardware, etc that we take for granted. He has his Chef hat on all the time cooking and restoring nuts and bolts and then has to deal with the missing or wrong hardware. At least there are a lot of parts sources for the Ford products.
I believe the Buick Nailhead engine was only produced through 1966, so while there may be some engine parts available here, I'm sure it would be a even greater challenge there.
The plus side on the Ford FE engines is being produced from 1958 through 1978 on production vehicles and for another 10-15 years for Industrial and marine use. So there were millions of these engines built and parts availability is beyond fantastic for this Ford Workhorse engine!
There are also dozens of vendors that handle body and interior part for the full size Fords. I had no ideal how many until I was given the task of finding interior and body parts for our body shop Managers 1965 XL Galaxie that needed everything!
Both the 60 and 61 Starliners Don C posted are pure car porn to me. Either would look good with you behind the wheel. The members of a local Galaxie club had a couple of Starliners in their ranks. Everyone liked the side view of both cars but felt the 61 had a cleaner, smoother grill appearance and liked the smaller tail fins. (Which were gone in 62) . They felt the 60 had a more cluttered appearing grill and had the love it or hate it "Bat Wing" tail fins!
When you finish your 73 and decide you need another project (Starliner....Starliner....Starliner......) just be sure you let us know and that way if you get in trouble you can always tell your wife it's our fault you bought it!
