Cabin noise is good on the cla, occasionally you get a bit of wind noise on the windscreen but only noticeable if there’s no radio on
When we ordered the cla there was a polar white cla next to a diamond white a class and it was a nice sunny day and I thought the diamond white looked a bit creamy yellow almost like the clear coat needed polishing, it would probably look different on its own but next to a solid white car I wasn’t keen.
