Looking for advice. Want to build a Duster to run on a budget.

My car isn't for sale but if it were it would be a good bargain for someone that didn't want to spend a lot . And just like it wouldn't be practical to spend 20 hours buffing a 5000 dollar car it would not always be practical to put thousands of dollars of metal and time into a lower value car in the marketplace .
Stop trying to justify chicken wire and bondo. It’s NEVER ok.
