When engine turned off it sounds like someone blowing across a milk bottle, and yes there is smoke even when switched off.
I park on the road, where a lot of pedestrian traffic passing to the local school, and get a lot of people knocking on the door saying your car is making funny noises/on fire.
But in the middle of winter when you spark it up, hit the heated seat and heated windscreen, all the insults from the "wet elbow" defender brigade seem to fade away!!
