Besides seeing what might be film crew member's cars parked or driving by multiple times in episodes of both Emergency (light blue VW Bug) and Adam 12 like this Mercedes SL there is also something that a few city car drivers used for parallel parking. Can you spot it in the third image?
I used to see Mercedes SL's parked around LA like that. The Robinson's Dept store in Beverly Hills used to have a ton of them in the parking lot when we were kids shopping there. Looked like an MB dealership.
Not an uncommon look to me.
