I have to agree with a lot or almost all of what oldmanmopar says. Been there done it seen it heard it.
People now days restore (try to ) cars that back a few decades ago were not even decent parts cars. Does not make sense to try to save every old cars you find. Many are meant to be donor.
Back then hardly NO ONE wanted a slant or 318 anything. They were parts cars.
Repop parts back then was little to nothing. It took bone cars to build a desirable car.
Here in SE Tx it is not a kind place for cars to sit outside. Too many trees, leaves and pine needs. Too much humidity. I look for projects West of here, few trees, and little humidity! One thing for sure, NO salt!!
Price of stuff? I lived for 39 years in Missouri. Especially South West Missouri is an old car area. NO where near the pop. as back East but Old 66 runs thru and always been a car area. Lots of Mopars too, even after R and R bought many of them up decades ago.
But it is a lower income area, everything there is cheaper than many states. Cars , parts, mechanic rates, etc. My mentality of what a car or parts is worth is based on my experience there. Now I realize the part I want in Pa. might be off a difference price range than Mo.
Who is selling that part. If the guy selling parts is like Oldmanmpar, he knows the market and is market.. Now the newbie parting out an old Volare may not be quite knowledgable. Maybe he just wants to make a buck to fund his builder, and has no idea that the 3 spoke steering wheel I asked about (on FB Volare site), of that Volare , that is cracked and needs major work, is NOT going to bring $150 shipped! H figure this out after a couple months and then asks me for an offer. Already found one on a bone car for $20. What is it worth? $20 or $150???
