BMW 635i, 645i, 735i and 735i can be used to create visual special effects in dancing clubs. The talk is about a beautiful, white-blue cloud a'la cumulus from the exhaust, which does not make the owner happy, but can be amusing to strangers. Especially in Poland.

It is a typical fault in these models, and we - unfortunately - learned to eliminate it in a clever way, making sad everyone who watched the show, but delighting the poor owner of a car. Sadly, the car cannot be used as a smoke generator in dancing clubs. The first cars caused us trouble, but now it is a daily bread for us. See if you can spot the same effect in your mirror.
