Yes, if those types of people are your primary customers. I personally hate those types of jobs. First, it is very disgusting. Second, these people usually do not call again soon. Some may wait another five years until the car is trashed again.
Ha ha. Same here in NOVA. Most Cayennes are filthy on the outside. God only knows what the inside looks like. I can not see spending $80 grand plus for a car and then letting it get trashed.
