With most any cleaning/ detail job the size of the vehicle plays a big part of when the vehicle will be completed and the final payment for the work completed. I do have a knack for getting done with a detail sooner than what I say initially. This doesn't work out for every job. There are jobs that will take longer than estimated. All I ask is to be patient and understand, I'm only making sure that you are happy and oversatisfied with the end result.
