Well I've done more research on the town, Found out that the population is larger then I thought, theres 8000 people within 10 miles. Being that theres only one other drive through ss car wash I feel that it's really feasible. The area has a great mixture of hot, cold, snow and rain.
I have an accepted offer on the wash with an inspection condition. I'm going to head out this week and spend time at the wash and do a traffic count going through the wash now. I've looked at this from all angles and believe it will make money. Guess there's only one way to find out!
