i was in this same boat back in april of this year..2015 or 2014 nismo..since its a few grand youre saving..considering everything else is about the same..the deciding factors for me was the 2015 body kit and recaros, sure you can buy the front bumper, paint it etc..but the recaros in the 2015 are like $6k a pop..making it $12k for the pair if you were to buy it from the dealer..and yes there are cheaper options with aftermarket but these bucket seats have airbags built in! and whats safety compared to a few bucks
also keep in mind our cars havnt had crash ratings done like other competitors..and there is only the standard air bags in the car so i plan on keeping all of them just in case
