I don't own one (yet) but a few mates have called them "Mummy's boys' cars" when the discussions ventured into cars. A couple of them would also mention how Supra's were better ... fans for the fnf movies
RE the top gear episode - I'm fairly sure the comment wasn't directed at Skylines but at GT2's (or a similar Porsche). It was the episode where they enter into the 24h race with a diesel BMW to use up their "bio fuel" they planted in the previous season.
I think this is it -> http://www.youtube.com/watch?v=8eZt9_7VV-I
EDIT--Wrong episode. It was the Alpha Romeo's Episode ->
--/EDITFrom memory, they've used a Skyline in the episode where:
1. They try to find the 'best' handling car ->
2. They drag it against a Mcleran ->
And of course the R35 in the near past racing the bullet train in Japan.
Sorry for venturing a little off topic
