Anything can be saved with enough $$ thrown at it, that said IMO this whole situation is indicative of what has gone wrong with the hobby. Everyone asks "what could it be worth" as pretty much their first question. Yes building cars is a losing (financially) proposition, but that is why its called a "hobby" not investment capital. If you are buying cars to flip then you are car salesman (not a bad thing) but if you love Mopars and always wanted a TA, you are going to be hard pressed to find a real one for less money. Yes it will cost you boat loads to restore/repair etc but in the end it is still a real TA. Put it this why, it cost the same to restore a 318 car or a 340/440 etc car but which would you rather have in the end; a bona fide RT or TA or a 318 or 6 cyl car? If the answer is "I don't care" then you have your answer where to start. If it does matter, then you also have your answer. I have a 70 RT which I bought for $5k 17 years ago, it was a basket case for the most part, I have worked on that car ever since and while it is fun to ponder its value, I know I wont sell it so it doesn't matter.
Sorry for the rant..
