I will say the business has been good for me, but is getting more challenging to net what I did in years past.
Metro areas in the southeast are overrun with express washes. Good business people have indeed closed shop here. You might do everything right, but if someone else decides to actively pursue your customer base with a better model, you will take it on the chin. New investors have developed a clear preference for the express model, and an area overbuilt with express washes is worse than an area overbuilt with IBA/SS washes. Expresses 15 minutes on either side of me has skimmed some cream out of one of my washes. My gross is down at one place 20% from the highs. Some local (admittedly probably not the best)operators have experienced much worse,with revs off 50% or more.
From what I gather small markets ( too small for expresses) and other areas of the Country that have not had the express model steamroll in seem to see SS/IBAs holding up OK.
So depending upon your circumstance there still is potential for making money in this industry. My advice is basic: Don't pay too much, run a good wash and get it paid off as soon as possible.
Oh, yeah- I would recommend at least calling your areas planning/zoning to make sure a new car wash isn't coming into town.
