I always seem to have trouble finding decent BGs for interior vehicles.  Most library recordings are all focused on outside the car with very few normal driving from inside perspective.  I have recently stumbled across Le Sound and their instruments.  The Wind, and Rain are amazing.  The Motors is a bit tricky and I have quite figured out how to properly use it.  Anyone use Le Sound Audio Motors Plugin care to share any tips on using it, whether for exteriors or interiors?
