I used to go to CARs too, was a member there for a year.

Half the time I sent my car there, they said there were too many cars and turned me away. The times when I went really early and was one of the first cars there, they would say it would take an hour. But of course, I would come back 2 hours later to find my car unattended/in the wash/parked to dry...basically anything but ready.

Of course, it wouldn't be fair to only mention the bad. They did deliver the car to me at the promised time before. Once. One time in an entire year. Their wash quality is nothing to shout about either, they don't clean the hard to reach places unlike some other car washes manned by foreign workers.

So nowadays, I send my car for washing elsewhere.
