Whatever you do with it, you need to really want the final outcome. If you've always liked the idea of an Eleanor, then go for it, they are great looking cars that really seem to hold their value. If you feel your car is rare enough to restore and you've always liked showroom-stock vehicles, then do that. Be aware that stock cars with little or no rare options that are stock don't bring that much money. Fastbacks like yours are valuable cars to start with, so assuming you don't cut the roof off or do something similarly radical, it will always be worth good money. Personally, I bought my fastback with the sole intention of building a Shelby clone. It was a nice, very original car that had been garaged it's whole life and owned by the same lady since it was new. But it was also one of a million having a 2 barrel 289, C4 trans, 8 inch rear and a plain color combo with nearly no options, so to me it was a perfect candidate for a clone. Out came the orginal motor and I gave it away to make room for a 306ci small block. All the nice orginal parts, like the headlight assemblies, the quarter vents, the turn signal hood, and every saveable part that was of some value went on ebay for someone else to use to restore their car. The car is no longer recognizeable as the same car in any way shape or form, and that's just fine with me. Now if it were a 390 GT with all the bells and whistles, I would've restored it, just as you woiuld likely restore your car if it were some highly-optioned car, right? Do what makes you happy with the car and you'll be fine.
