I'm interested in getting one of these cars.

the s2000 is an 01 with 30K miles titanium ext $21,000
the 350z is an 03 with 24K miles black ext $23,000

what are the pros and cons on both of these vehicles?

I drove them both and I like them both but the 350z felt "cheap" in the inside but you can feel the torque and the s2000 being a 4 cyl drove pretty good.
