NISMO 370Z is heavily overpriced for daily driving. If you like it for looks, get the body kit and exhaust upgrades. It should net you over 18whp anyhow.

335i is a very nice car, and you can't beat BMW drivability. It definitely had upgrade potential to overpower it's curb weight and outrun the 370Z. I wouldn't consider it much of a track car... you may want to consider a used M3.
