Import Magazines have somewhat evolved who they feature and it's always changing. Some I'm noticing are focusing on the more "trendy" cars you see online, but are not "complete builds" like the old days of feature cars. Other mags look at performance first, but aesthetics is very important too. It's safe to say that if you have to have a pretty nice car and stand out somehow, you have a good chance to get it into a magazine. Having an NSX is especially an advantage because it's still a very popular and sought after car. Funny story, I was talking to an editor friend of mine @ a very popular import mag. I pitched one car to him and he said that although it was a very well built car, they limit that platform to about 1-2 features per year since it's not very popular. Since you mention Honda Tuning, I can tell you that all you need to do is to send some pics and mod list to your photographer friend who shoots for them. Honda Tuning is one of the mags I shoot for and if I see a car I like, I will simply send the editor pics and a mod list to see if he's interested. If he like the car, I'll then schedule a shoot.
So bottomline, have your photog reach out to the editor and it will be either a yes or no.
