Been going to Mammoth for years now, and have never had them do my car wrong. The employees are always happy to see someone returning. It's simple drive up, tell them how you want it washed and then any extas you need/want. Then walk into a luxurious room to wait. Average wait is about 45 minutes. Sometimes you can find some unique conversations with other drivers. It's all about making your cars look the best that they can.
