several luxury car manufacturers offer models with built-in fridges or coolers. These fridges are typically designed to keep beverages and snacks cool while on the go. Keep in mind that car manufacturers frequently update their vehicle offerings, so it's possible that newer models have been released with built-in fridges since then. Here are some examples of cars that had built-in fridges as an optional feature:
Rolls-Royce Phantom: The Rolls-Royce Phantom is known for its luxurious features, and some models offer an optional built-in fridge located in the rear center console.
Bentley Mulsanne: The Bentley Mulsanne has been offered with a rear-seat refrigerator option, which allows passengers in the back to access chilled beverages.
Maybach S-Class: Certain Mercedes-Maybach S-Class models have been equipped with a rear-seat refrigerator box between the two rear seats.
Audi A8: Some high-end versions of the Audi A8 sedan have been available with an optional rear-seat refrigerator integrated into the rear center armrest.
Tesla Model S: Certain versions of the Tesla Model S have been offered with a rear-facing third-row seating option, which includes a rear console with a built-in cooler.
Cadillac Escalade: In certain configurations of the Cadillac Escalade, you could find a rear-seat refrigerator installed in the center console.
Remember that these features may not be available on all trim levels and might be optional extras that you have to specify when customizing your vehicle. If having a built-in fridge is a specific requirement, I recommend checking with the latest models and configurations from these luxury car manufacturers to see if the option is still available or if any other brands have introduced similar features in newer models.
