That red is dead-sesky, I tell'ya. If I was 10yrs younger and/or it was for my mom/wifey/daughter/etc, that would be an exterior finish I'd find hard to ignore as it truly looks great on the CLA! Some tints, gun-metal wheels... oh-lala!
Never say never, man! I can see those wheels being a premium stand-alone option that can be dealer-installed (instead of ordering on the car as the 18" stand-alone option or the Sport Package 18" setup).
AMG Boost had a great suggestion that we sticky a thread that contains posts/pictures from owners of their brand new CLA's... So, without further delay, here it is! Post pictures of your brand new CLA in this thread.
