lol, I still have absolutely no idea why people talk about the E46 3 Series interior as if it's some kind of Bentley, compared to the E9x. To clear up, it most certainly is not.
My E92 interior was a much nicer place to be with everything feeling sturdier and more solid. Both of my E46's (which were/are in very good condition interior wise) and other peoples E46's i've been in have not been bad places to be by any stretch of the imagination, but certainly aren't the last word when it comes to interiors, and certainly don't justify the "OMG GONE ARE THE DAYS OF THE E46 INTERIORS" comments.
I am not an interior whiner, but the centre console is rubbish in the E46, from the squeaky/rattling armrest to the cheap slide back cubby hole. There's also the rattling from the HK sub if you turn the bass up too much and the steering wheel is so shiny i'm worried magpies might try and take it. Oh, and the glovebox feels cheap. So does the cubby hole by the drivers knee.
The only thing that annoyed me about my E92 and my mums E9x is that the sunvisors are made out of the cheapest material known to man (although it's not exactly good in the E46 either) and there was a rattle from my rear cubby hole slider, which was caused by the Milltek exhaust, so that doesn't really count.
