I own a S2000 and my GF owns a G35.

- S2000 is cheaper to fix/service.
- S2000 is still more of an import.
- G35 for backseats,heated/powered seats, bose system, etc.
- G35 6cyl is a smooth ride.
- S2000 has less kick to the rear (fish tail)
- G35 got traction control (AP2 s2000 has it as well)
- Convertibles pulls more girls. lol
- G35, dont have to worry about anyone slashing your roof to steal your damn seats!!!
- S2000 cheaper to mod.

Thats about all i can come up with for now. I love my S2000 but sometimes i would wish for a little more room, so i drive my GF's G35 then. I Rather get a G35 tho bc its more of a sport and luxury. Can look good and can go fast. When i was buying my S2000 i woulda bought a G35 if my gf didnt have one. I would still choose it over my S2K.
