This rating/comments follows a 30,000 to 50,000 annual service requirement for oil change and book inspections and service. I was positively surprised with improvements on my VW Passat performance as a result of your service. I first noted that acceleration had greatly improved as I had to push it a bit to merge with the traffic flow. Next I found that the steering, which had been very heavy ever since I purchased the car, now feels as if a huge weight had been lifted from the front of the car, removing almost all of the back pressure to turning, really much more pleasant handling. As usual the anticipated cost, time, and points covered were discussed before the service started and no negative surprises were experienced.
