I bought my Tudor all in pieces. I had no choice but to do a complete frame-up restoration. For the past 10 years, the car has served me very well with routine maintenance and a very few, very minor issues. Everything works as Henry intended and I am very comfortable taking it any where including long distance tours.
I bought a Vickey about 5 years ago. An older repaint and upholstery and some other repairs. It looks good but has issues that someday would like to deal with. I have fixed the brakes, differential assembly, radiator, generator, distributor, water pump, door latches, locking door handle, window channels and a bunch of leaks and rattles. It is fun to drive around locally but the engine has some strange noises in it and it should have a new top. It is fine for local driving but I would not want to take it any distance from home unless I do something about the engine and put some new tires on it.
So it gets down to what you expect from your Model A, how much of the work you can do yourself, how much you enjoy working on the car, and how much money you want to spend.
I do know trying drive something around that is completely worn out is not much fun. and there are a lot of Model A's out there for sale that need a little work and some TLC that would make nice dependable cars for not a lot of money. I also know that you will never recover the cost of a complete quality frame-up restoration when you sell the car.
