Mo, the service advisor, was able to help out my son on a Saturday morning since he was stranded while doing a road trip in a Chevrolet Express. Fortunately they had the spare part in stock but he accepted to do the work even though they were fully booked. My son and his girlfriend were able to continue their road trip! Kudos also to Cat (customer service) who was nice enough to let me speak to Mo to check if he could do something for them. Thanks so much!
