You're the poster boy for why it's a bad decision for the OP to hang onto the project.
You've paid for years of storage for projects that are still not roadworthy today.
I haven't paid for storage for the car I've had for twenty five years, so it cost me nothing, you twisted that one to suite your argument.
I have paid for storage for projects that are indeed not roadworthy, luckily I have super cheap storage, and I'm okay with the money I've spent.
Why don't you tell us what has prevented you from having your projects plated, insured and ready to be driven anywhere with the turn of the key today?
If you actually read my posts, or threads about my cars, you'd see a pattern of me buying cars when I could instead of putting that money into one car. I got my Polara to flip, and it instead started my love of '66 Dodge C body cars. I wouldn't change that for anything. So I kept buying more cars when I could while still working on the ones I already had. I don't care if they are showroom quality cars, I get more enjoyment from my Scruffy fleet than I would a fresh restoration. I still hope to restore my four speed car, but if it doesn't happen I won't be upset, the car will get driven.
I have two cars I can get in and go, another that needs some wiring and it'll be back on the road. Some of the cars I wanted to get on the road will become donors for the four speed, the greater good philosophy. No one wants to sell a solid car for cheap, so I'll cut up a car I got for cheap with no title to make one car with good sheet metal. They are all.plated but the one with no title, so that's not an issue, and I never need to pay for registration again.
I didn't care about having a bunch of money, it's not that important to me as long as I can cover my bills and have some fun as well. I didn't actually start building my credit or bank account until my early 30's, and again, I'm fine with that. Known my house free and clear.
I had to buy whole cars to get the parts I wanted, and I sell off the parts I don't use. It's worked out well for me to have the spares I need, and a side hustle for what I don't. I only had three old cars until 2018 when I started buying more that were good deals, like my '68 Monaco 500 that gave me 10k miles in two years before I sold it, and turned my focus back to my '66 Dodges.
If I was 20 all over again, I don't know if I'd change anything, I've enjoyed my life so far, and my love of old cars has led me to many great friendships with people all across the country. If I would have sold that Dart years ago, I don't think I'd be as happy as I am today, but who knows, you can't predict what didn't happen.
I will agree that these cars are a money pit, but it doesn't mean one has to sell just because there isn't a bunch of resources at the moment. To each his own.
Does any of this matter to Isaiah and his situation? No, not at all. But I'd love to visit him and take a ride in his lowrider when he's done.
