I could not agree with @AceAndrewmore. I am, like some on this forum no doubt, are products of the 50's and 60's were hotroding found its birth from those who were able to return from the war. They used their ingenuity to create something that would occupy their time and reap some sense of accomplishment. They did not have much money to carry out their dreams, so they scraped and scrounged to find the pieces to make it work. I am sure they did not care about aesthetics or resale value or safety for that matter. They continually pushed the envelope to suit their sense of style and needs.
For me personally, "I saved my pennies and saved my dimes" (to quote one of the great 60's contemporaries***) and bought a 55 210 Chevy while I was in High School. It took be a couple of years to complete the mods but it was just what I wanted, it wasn't that unique in the scheme of things but it provided me so much enjoyment. It also led to many relationships that have stood the test of time.
So I am sure you asking WTF has this to do with your plight. Well , if you have not guessed by now I am not in the purist camp on this one. I have owned my 2002 for some 47 years now. It sat in my garage for close to 40 years collecting both dust and disdain from my entire family before I was motivated enough to breathe new life into it. I never lost focus over those years, I knew exactly what I wanted it to be and what it was gonna look like and how it was to perform. Not ever did I concern myself with what will it be worth at the end of the journey. It's just simply not part of my hotrod DNA.
So, I saved those pennies and dimes yet once again for my last 'hot rod" project. It took me 6 years to complete, never did I loose focus. This site had much to do with that for which I will always remain grateful. So you have found the right spot if you need help.
Finally, please don't leave with the impression I do not appreciate the pain stacking effort and dedication it takes to truly restore one of these classics. I really do. It's just not me. So if you are a true enthusiast, your heart will guide your way. If you are concerned about the ROI, I think you need to find another venture.. Your WILL to complete this project has to be greater than the concerns about its financial rewards. Its all about the process, IMHO
Good luck with what ever you decide.
