I guess it would be a petty fair trade. Depends on what you think you would have the most fun with. In my opinion neither one is going to have a big deal price increase, Although P/Us are starting to be desirable. There is a pretty good following for the Birds also and good parts availability. If you like to go on longer drives you would certainly have more comfort in the T-Bird. I think it may copme down to a personal preference rather then a value thing between these two. I have both and when I want to take a nice ride out comes one of the T-Birds! BTW my 53 F-100 kinda like yours.
