I get some admiring glances directed towards mine too. Interestingly, my mate has a 996 carrera 4, and he complained recently to me that he got lots of general aggression- I found it hard to believe until we went out for a bit of a razz in our respective babies. At one memorable set of lights, he got some V-signs from the kerbside chavs, but I just got some "hmm, looks nice, not sure whether to abuse you or just look on admiringly" from the said chavs.
I actually think the Nissan badge works in our favour sometimes- makes it a bit easier for people to relate with us, and doesn't generate that "them and us" feel that pricier supercars do...
Just my tuppence
