The only reason I could see for using the undercarriage spray would be to get to the rear suspension components, but I'm not sure if there's much of a point in that and the automatic undercarriage sprayers usually only spray the center of the car.
That's right, I'm spending most of the time spraying the rear suspension area. I do spray the underside but that's mostly hoping that the water gets into the areas that have slight gaps.

To be honest, the majority of what I spend my time washing is at the bottom of the doors. I find cars tend to rust there first and my friend who had an M3 said his old M3 started to rust there too.
