ONE STAR. I've been to Montgomery Hills Car Wash several times and usually they do a great job. Today, however, they REFUSED TO WASH MY CAR. I asked for the regular wash ($13) and was told my car was too dirty and that I would need to get the ultimate wash ($22). Admittedly, my car was pretty dirty, but that's why I went to get it washed in the first place! Moreover, I've shown up with an equally dirty car to this car wash before and have found the regular wash to be more than sufficient. Nowhere on their website or any of their signage onsite does it stipulate that a vehicle may be ""too dirty"" to receive a certain type of wash. Not only did they refuse to wash the car, but I was treated rudely by the staff (particularly the gentleman that seemed to be in charge outside). I will not be visiting this establishment again and suggest you consider taking your business elsewhere.
