67 SS El camino 72 SS El camino

I came across a 72 SS El camino W code with original drivetrain and sheet metal. It has cowl hood, air, factory wheels and the rest of the usual options. It is stunning and was just curious as to what it might be worth?

I also found a 67 SS El camino was a 396 car but now has a 427. It is royal plum and all original sheet metal car also. It is a stunning car, very very clean. Any idea as to value of these?

Oh, both of these autos need nothing and are in heated garage under cover.

Thanks for any help
