In the first two series, Inspector Darblay is seen driving an orange Austin Mini (licence registration RVH 873T). In the third series she is seen driving a pale yellow Austin Mini Metro (licence registration MVP 519W) which, in episode 4 "Amateur Night", she can be seen parking next to an orange Mini – possibly the car used in the previous two series – in the car park outside the "Hartley Little Theatre", except for episode 5 "A Breach of the Peace" where she is seen driving a marked Ford Escort police patrol car.
