Certainly, if you're in love with '69 Fords, the convertible is the most desireable, and therefore "valuable" of that vintage and model. That being said, look at the market for '69 Fords..........not very high. If you looked around real hard you could find a cherry one for less than $10k. And unless you're a very skilled metal man who has a lot of time on his hands, or the patience of Job, you're not going to make the car you described nice for that kind of money. As an example of something comparable I offer consideration of the '67 Merc convertible that AHSOM70 just bought for around $4k last week.

Saving an abused drop top is no small task. And after giving you the gloom above I'll tell you about an insane person I know who did just that. It's a '36 Ford roadster. Each door (unique to roadsters) came from a different donor, they both needed patch panels at the bottom. The top of the cowl, and the tulip panel (again unique pieces to a roadster) were taken from another car that had virtually nothing else left worth saving. The lower part of the main body section, with deck lid, came from a '36 five window coupe. Of course it needed patch panels at the bottoms of both cowl sections, both quarter sections, and the tail pan. Oh, and it needed a complete floor. So far I've described pieces from 4-5 cars, plus some aftermarket repair metal, just to make a main body. Several more '36 Fords contributed fenders, hood pieces, grille, windshield parts, etc. Why would someone go to all that trouble. Reference the insane remark above, but also these cars are both rare AND valuable. Not all that is rare is considered valuable. It comes to personal choice. This idiot wanted a steel '36 roadster, and had both the finances and persistance to make it happen. You need to determine if you possess the same desire, financial wherewithall, determination, skill and persistance. Then act appropriately. BTW, you can see pictures of the roadster in my gallery.
