I had a very pleasant experience during my first visit to the service department of the dealership. They were very busy and it took one and a half hours for the 7500-mile service to my Buick Regal Sportback. The time flew as I was able to catch up with news on their television. I was still in the parking lot where the car was parked after the service job when I noticed that the air pressure was still low on all four tires. A very pleasant and helpful technician took care of it right away.
