I'm guessing ashtrays are no longer optional equipment in British cars.

An intriguing question.  I'm not seeing any evidence of an ashtray in the interior photo of this Land Rover model, and none is listed in the "accessories" section for this vehicle.

(note that even though I specifically went to the Land Rover UK site, they are using left-hand drive vehicle images)

 

However, it appears that an ashtray is still standard equipment on the 2008 Lincoln Town Car, as evidenced here on an image from the American Ford site:

 

I'm not seeing the Lincoln as being available in the UK, so I can't compare.  Land Rover is now owned by Ford, however.

Now being used to Brit cars and there layout, I spotted the ashtray straight away. Its to the left and just below the gear shift (in the picture).
My car has an ashtray (not that I use it), and it wasn’t listed in the accessories when I bought it...........
