65 barracuda 273 From the dead

What do you mean hobby

What value difference between original tan color versus flag colors

And I sometimes do temporary paint jobs with good quality

Any idea what a 65 barracuda 273 a little more than mild build automatic. Mostly gutted inside but very straight and all trim is there
What's it worth
Passion, Interest, hobby. None of what we are doing in a necessity to our lives just fun.
I am not saying that there is a difference in value but it might deter some buyers while attracting others. So it could make it harder to sell versus a more conventional paint jobs or it could make it easier. I don't have a pole of who vs who wouldn't buy an american flag car. Nothing against the flag but it could be a little much for some buyers. Again it is personal preference.
If you are okay with doing temporary paint jobs go for it.
Not exactly but I would guess maybe around $4,000 or so (based on what I paid for a 1 family owned dart with 60,000 miles.) I am not sure and don't really care about your finical details but sometimes you need money in a hurry and most people dump luxury items first like classic cars boats etc.
