Those '59 Bonnevilles were nice! And some of them did have leather trim in the interiors. Here's a fairly recent pic of my '67 Catalina:
The wheels are not period correct, as I don't think the Pontiac Rally II wheel came out until 1968. And I don't think you could get it on a full-sized car until 1969. But this car originally had 14" rims, and kept throwing hubcaps. I got tired of chasing them down, and wanted a beefier wheel/tire, so I upgraded a few years ago.
Here's an older pic of it, with the original wheels/hubcaps. This was taken in 2006, right after I had my garage built...and when I really could get 4 cars in it, before I cluttered it up.
