Looks perfect
Was a little hassle to install, not going to lie, the cupholder didn't want to stay in place. After some brain-power, came out great 👍.

OEM fit, pattern is not the best
The product fits into your E46 center console perfectly. Locks in place. Great replacement for broken or worn out cup holders. The "carbon fiber" pattern leaves a lot to be desired. It was obviously dipped and the patter is skewed and very fake looking. I wrapped this with a carbon wrap and it looks fine but you might as well get a black one instead. I only gave it three stars because the fit is great as expected but the whole point of buying this one was the carbon fiber appearance which is poorly done.
