I brought my 2016 Silverado in for routine service 2 weeks ago. This is the same $5Ok truck I bought there in July 2016. I picked it up when it was rainy afternoon, but a day later when weather was good I noticed a big scratch on the passenger rear panel. I called to notify the advisor (Rex, and he said he spoke with Joe), and there was nothing they could do about it and they wouldn't take responsibility for it. This place lost a customer and future sales. I was planning on a $80K Corvette down the road, but due to their disregard of doing the right thing I will no longer buy from a place that cannot take care of people's property.
