I've had a X5 4.8iS/E92 M3/TVR Cerbera 4.5 which were all more powerful than my 370Z, but what attracted me to it was how much I loved my old S14a 200SX(modded to around 250bhp).
I didn't buy my 370Z for its performance, because compared to many turbo engined cars nowadays the 370Z is actually quite slow in comparison. I just seem to have a real soft spot for a Nissan performance car, and I just really enjoy owning and driving them for sure.
