I would go with the s2k. For the reasons of there will be tons of 350z's on the road i am ready see way more z's than s2k's due to the fact nisan already produced more z's in one year than honda made s2000's in 4 years. The z also looks to close to an audi tt and the infinity g35 nothing looks like a s2000. Just my 2 cents get the car you like more.
