A few months ago, I stumbled upon a program called Miss Fisher’s Murder Mysteries. Set in the '20s, it seems very authentic in every way–including the cars. Ms. Fisher–who is independently wealthy–drives a Hispano-Suiza, frequently at high speeds. It is not unusual to see vintage racers from Alfa Romeo on the program, as well as Vauxhalls from that era, a number of Ford Model A coupes, and a lot of cars that I can’t identify. The episode that I just watched even showed a nice SU twin carb setup under the hood of one of the cars.
As a bonus, the star–Essie Davis–is incredibly beautiful, so there are a lot of nice sights while viewing that program. This program seems to run at odd hours on almost all of the PBS stations, so you will have to be vigilant if you want to see it, but if you like murder mysteries, vintage cars, and beautiful women, I think that you will enjoy watching this show.
At first, I thought that this was a British production, but it turns out to be from Australia. However, the characters all speak with a British accent, rather than an Aussie accent, so they are relatively easy to understand. Here is a link to the ABC (Australian Broadcasting Corp) website for the show:
