My belief is that anyone who is here on this site has a passion about cars, and is very discerning about their vehicle appearance and maintenance.
For those not on this site, that group still exists. People that have a passion for cars and is extremely discerning about the appearance and maintenance of their vehicles yet do not have the time, knowledge nor desire to do the work themselves.
That is the particular group I, (and I'm sure many others on AGO), strive to reach.
There is room in the whole spectrum for local car-washes, franchise car washes, dealer detailers, etc... Much like there is room in the market for fast food chains all the way up to 5-Star Bistro's.
What we provide here on AGO is boutique, explaining that to the layperson is where the skill comes in.
