I have been going to Lexus Concord for service since 2008 and I just came home from 90000 miles service.It was always good to have service and a little extra cleaning inside and out.
This time I even told the agent Brian that I hope they vacumn
my car and he said'" Oh for sure they did that.
Well,I came home and looked and all the sands under all floor mats were still there. He probably saw my car looking clean and did not bother to look closely.
Please tell them not to presume it is clean.
