I dont' think it's a trailer Queen in the least. That is undercoating, worn and bent steel, and years of dirt and grease coated parts and sheetmetal.
Not to get on a high horse or anything, but again, the car hasn't been described in the least. Furthermore, to sell a car for the kind of money they are talkin', they need it restored to be about perfect. Seat belts with date codes, original glass all around with Carlite logo, all rechromed or originally perfect Chrome, polished stainless everywhere, restored front grilles, emblems all NOS or perfect rechromes..springs and coils clean, all wires and vacuum hoses marked, all over marked with paint marks, carb, rear end, and engine tags..concours like. Original-like. Is that all done? Hmm..we don't have any idea, but I suspect not and see a lot of crud on the underside (at least frame and front suspension components, not much else visible!)
If I'd done all that or it was all perfect or even there, I'd sure as heck be advertising it!
I'm just sayin'
