That is a nice set up.
As I am always searching around I have noticed this attachment online and if you dig, they have adapters to suit most brands. Not sure if it will fit under a Mustang. Might be good for a 4x4 or normal height car.
What I am more interested in is the replacement Lance with the angle at the end. With the angle it lets you get between the spokes of a wheel to clean behind. Also helps with the inner guards ect.
The standard ones are straight so this I think will be a good upgrade to add to my list.
