Buy the Nismo! Besides the excellent Recaro seats and body package, it comes with a lot more handling goodies than most people realize. Having driven both a sport package and a Nismo, there is no comparison. The Nismo feels like a different car. Best handling and visceral car I’ve driven so far (in stock trim). Plus, you’ll be driving a much rarer car.
But, I may be slightly biased so take my advice for what it’s worth....
