No way, I would definitely not trade a 335i for a 370z and his 335i is practically brand new as well. 335i is a more refined machine overall and carries luxury options that can't be found driving a 370z. Plus a 335i is more practical as it can fit 4-5 people with a decent amount of trunk space.
Performance-wise they are about the same but the 335i Turbo engine is a lot easier to mod that the 3.7L on the Nissan. I can understand if he wanted to trade a 328i, but definitely not a 335i. The BMW is superior is every way.
