What is the most you'd ever spend on a more door ^A-body (non wagon)

After 35 years in the Mopar hobby, I have my first more door, a 64 Belvedere. I have sorta wanted a four door for a few years, but I got this car on a trade. It is a 95% rust free and a runner (318 PB). I love the early Bs.
The good part is I traded a Wagon I had $500 in. so my inititial investment is nill. I did the body/paint work, tuned it, did some brake and exhaust work, new tires, got it where you can drive it anywhere. I had to get a bonded title. Bad part is I had to replace the windshield and back glass and gaskets. That added another $1000 to the ledger. I replaced the front seat with new Smittybilt A100 style buckets, windlace and carpet. I call it 98% done. Needs headliner and a little wiring work on taillites.
Here in Tx it is not a hotbed for Mopar. I have had it listed on FB Marketplace and elsewhere for $5500 for a couple months or so.. I have had one offer of $4000 over the phone.
My point is STILL, most people think of more doors as only parts cars. Not that many people that want them. Only reason I have some cars for sale is I'm 74 and hard to finish projects. The more door is just about done, so IF it the last one to sell, thats fine with me. I like it. If I work for FREE,I could sell it for $4000 and not lose a nickle, I just hate doing all the work for free. $1500 labor for body/paint work is almost FREE!!!
If a person got a more door project for free, and he did all the work, and never wanted to sell it,,, he might be OK!!!
Sorry if these comments go off track!
