LOCATION, LOCATION, LOCATION
I dont care new or used, if your not in a good location then you really are hurting your business. I see some people say that it does not matter where you are, if you are good people will come to you. What i have the say to that is "bull$hit"
People do not want to drive 30 minutes to go and get a wash or a detail, yes you may have some customers that dont mind but others do. Look for a local area with a lot of traffic. You will get the drive in for a quick wash and get some detail jobs from it as they look at other cars you are detailing while they wait.
I know some people may disagree with me, but this is what i think you should look into before you find a place.
