I've clicked on Sub-zero because apart from the styling, of both Spider and Coupe, the fact that they had Ferrari engines but weren't Ferraris speaks volumes.
Contrary to the Top Gear proviso that a car can't be cool if you've got to explain what it is, to me, that's just what makes the Dino really cool. Only those who know their classic cars actually know what it is. You can buy a BMW 3-Series with a 1.8 litre four cylinder petrol engine but spec. it with M Series wheels and you get a badge to go with it. Even coloured brake calipers if you like, but it still remains a "cooking model" and everyone knows it's a B-emm and almost everyone knows the "M" badge.
If I owned a Dino, and the Coupe would be my preferred model, then if someone asked me what it was, I'd just smile and not reply. If they have to ask, then they wouldn't understand.
