This taxi is filmed in an extreme close-up, approximately at 5 minutes into the episode (time stamp referring to the PAL version from the official DVD set; not the NTSC version or any syndicated versions).

I think the angle of the rear window and the shape indicates it might be an AMC Matador, but it's really difficult to identify the car.

Any thoughts on the make and model? Thanks for taking a look.

night cub -- thanks a lot. That looks correct, indeed.
