Well, fwiw, I watched in on normal re-runs when 99% of available tvs were b&w. Back when all of the other "cop shows" had Fords for police cars, or even some fast Chrysler products. The one thing I noticed on the Buick that Dan M. drove was how solid the suspension seemed to be, unlike normal Buicks of the time.
Other than the lack of "wind in the hair", I was amazed at how the cops and robbers seemed to shoot as they drove. Some of the things we missed back then, getting caught-up in the story line and execution thereof.
The local Decades TV used to replay vintage detective shows. Back when it was on a regular programming, I seemed to not notice that Peter Gun drove a '59 Plymouth convertible. I was more into the Warner Bros shows as "77 Sunset Strip" and "Hawaiian Eye", where everybody drove nice Fords (except for the "hot rod" that Kookie drove).
Nice to see how television "used to be", to remember the things of where I was back when I was intently watching each episode. And THEN came "Batman" and his flame-throwing, re-cycled Lincoln show car! I need to mention the YouTube channel for "car chases" and the CarIMDB.com (Car Internet Movie Data Base) searchable website, too.
Enjoy!
