I have an older Acura. The R12 needed replaced in the air conditioning. John at Auto Tune said they carried R12 but it was really expensive. He told me they had a similar product, Freeze12, that would work just as well at a fraction of the cost. They also looked at some other issues on the vehicle.
I was impressed that they offered alternatives that were much less expensive. I would not have known there was an option to R12, and they could have charged me a much higher price.
John was friendly and helpful and I will make the drive to take my vehicle there again.
