Nice cars. I remember the old days when the imported Nissans were something to enjoy, now they're like bums.... everyone's got one. Don't get me wrong, they're still nice cars, just not as much fun to look at when you see ten 180's or Silvia's(or Onevia's/Sil80's for that matter) or GTS-t's a day.
Having previously worked in the industry(
