I note that the petrol filler is located in the HPE position with an external cap rather than a flap. I recall that Lancia made that change in late Coupes, but IIRC the European Spider was phased out before that happened.
One thing that I have never quite understood is why the later injected and supercharged Coupes and HPEs were withdrawn so quickly, not just from the UK market where the rust legend had already set in, but across Europe. I know that the Beta range was by then over ten years old and had never had more than tweaks in terms of body designs, and the Berlina looked dated when the ugly Trevi was introduced, but to my eyes the Coupes and HPEs still looked good alongside early 80s designs. It may have been production costs and plant capacity as the Delta was taking up most of the money by then.
Apologies to any Trevi owners out there. Tastes vary, but to me it is one of the ugliest cars that Lancia ever made. Oops, sorry, thread hijack!
