That's what I tell everyone who complains about the beautiful imperfections of the Nismo... it's a sports car. I would have bought an Infinity instead if I thought the noise was going to be a problem but I knew the noise issue could be remedied with a fix. And isn'ton that why we buy narrow-focused sports cars so we can modify them...just like I did to to my 1969 Opel GT. I look at those times and compare them to now and feel like the Nismo a luxury car! (and the Nismo is a luxury for me). Guess the Nismo had spoiled me a little bit!
Incidently, I located the mic on the ceiling light dome panel...it can't get any closer.
Happy motoring guys
