We have been getting our cars washed here for about a 1.5 years. I am pretty disappointed they raised their prices (ok, maybe its not a "raise" but more of a consolidation of wash options making it more expensive to get the the same elements of a car wash while paying for elements I never wanted).
That being said, its usually worth it got have them vacuum and towel dry your car every now and then with cheaper washes in between. I don't have kids or a pet, so I can't tell you if they do an okay vacuum job....once I still had hair on my floor mat.....
Today I was there at 8:30 am on a Saturday and they were very busy. It must be a combination of the monsoons, dust storms, and the afternoon high temperatures that made them so busy. Even so, I driving away in about 15 minutes.
If getting the air fragrance, I recommend asking them to go easy. On more than 1 occasion, I suffocated on the smell on the way home.
