Yeah, the McLaren F1 is iconic and remains fresh-looking today. The P1 is but another mid-engine hybrid hypercar among many. Similarly, the D-type Jag is a better-looking car than the E-type, though I'll grudgingly admit that it's probably less iconic. The omission of anything by Lotus on the bracket is just outrageous though.

If the question was iconic, like you say it'd be much easier but then the P1 wouldn't even get a mention.
