My only complaint relates to the length of time I had to wait after the agreed comletion time. I delivered my car before 10am as scheduled but it was returned 45 minutes after the agreed time of 2.30pm. I also would have appreciated more feedback during the 45 minutes wait (indeed I had been in the service waiting area since 1.30pm)
Good experience. If anything, took a little too long. Waited in the office for 3 and a half hours. Of those three hours, I waited an hour and a half before my car was driven to the service garage for service.
