I don't know what kind of car you have, where you live, or what all you're having done to your car that it's costing you $150, but around here, it's about a tenth of that. For $15, you can have a four door car washed and dried (by hand) and the entire interior vacuumed. For double that, you can also have the vehicle waxed, Armor All applied to the interior of the car, and the tires detailed.If you're asking for a full detail with the seats and carpet removed and washed, you're looking at $150. It takes a bit of time to do also.
