It is actually pretty quiet compared to some other roadsters. Now, my S2000 back in the day was loud. If you are hearing creaks from behind or from the passenger side, I've noticed these 2 things:

1. The passenger side seatbelt might rattle some over uneven pavement. I had similar issues in my past roadsters. Plug the seatbelt in when its not being used. It solves it.

2. If you are tall-ish, (or your passenger is tall-ish) and you have seat all the way back, it is likely touching the rollbars and behind the seat. The leather-plastic rubbing squeaks alot. Unfortunately, the only way to resolve this is move the seats up so they don't touch. If you are tall, thats a problem. If you are a little shorter (I'm 5-8), I can just move it enough to not touch.

I made these 2 "mods" and the cabin is much less noisy. I mean, I don't mind hearing the engine roar some. Actually, I kinda like it most of the time. But I always hate the creaks, squeaks, and rattles. Its minimized quite a bit now.

Just a couple of small suggestions. Otherwise, like what others said: It's a convertible, its gonna be louder than what you are probably used to, esp. with the top up.
