My brother is selling his 56 Mainline, Looks like Walley's but its a 4 dr. He is asking $9,000.00. It is originally from Oklahoma or Arkansas, he purchased it in Missouri. Original 272, three on the tree, immaculate grey cloth interior. Not a perfect car but very respectable. Was restored by previous owner with full pictures and docs of the resto.
Its the red one next to the vic.
