Yes, agreed it looks nice. I’ll be the “downer†of the crowd. You state the PHS indicates 326, that car was repainted non-original color, new floor pans etc. All of that pretty much reduces the provenance to zero. I would think you could list for low 20’s and expect to end up in the teens somewhere...
