I've always had a great experience with this car wash. The machine does a decent job (as good as can be expected for a drive through washing system.)
The people who work here (mostly college and high school aged) pay good attention to detail and have no problem going back and doing extra wiping or vacuuming if they accidentally miss a spot. We have a 90 lb yellow lab, so our car is often full of dog hair and dirt. They never seem to have trouble getting it all cleaned up nicely.
If you want detailing level of cleanliness, get the car detailed and spend $150-$200. But if you want a decent quality cleaning that'll keep your car in good shape, this place is an excellent option.
And don't forget to tip the attendants! If you forget cash they can put your tip on a card and they give you a voucher to hand to your attendant.
