Coming from a first gen BRZ, this car is way quieter for me. The FL5 does have more rattles though. Now that I think about it, my car isn't much louder than my friend's 2018 accord either. Maybe my ears are shot...
Yea Cerritos is one of, if the not the biggest dealer in the US. Funny, they wouldn't even budge and match the offer of another local dealer last year. Now they're selling practically for MSRP.
I found a bunch of manufacturing quirks and imperfections already. As long as there are no leaks or serious issues, I wouldn't worry about it. It'll just drive you crazy ?
If you're willing to wait, I would check out Escondido. They do 10K markup, which includes a couple grand of accessories. They sold it the day I called them.
