Great looking rendering but the wheels look like they are 20". It's a common problem with vehicle renderings. Most of the time they are drawn with wheel/tire combos that are impossible to replicate in the real world. Then the actual car doesn't end up looking like the rendering.(which is the entire point of doing a rendering in the first place)
People tend to make standard whats popular now as opposed to what was real back then. Many younger people not old enough to have enjoyed these cars in their day probably think they came with 20" wheels back in the 60s and 70s.
