Truly awful experience!!! Made an appointment at 11:30am to have a "new-to-me" Corvette checked for recalls and software updates. After waiting for 10 minutes just standing around, I was approached by one of the service technicians that just said "Oil Change?" , I said no that I had an appointment, and the technician asked me irrelevant questions not pertaining to my vehicle or appointment. I was then asked by Kirk(Kurt?) why I was there, told him I had an appointment and wanted to check for the mentioned items. He states that there was no recalls, and that they wouldn't do any updated to the car unless there were issues. This is the first time in owning cars for 20 years that I've been told by a service adviser that updates would not be applied to a car. (What about improvements to the software, ECM, TCM?!) Then I inquired about an alignment, of which he said that I'd have to leave the car and they wouldn't be able to start on it until late afternoon, even though I had an 11:30am appointment. I'm picky about whom I let work on my cars, and as an owner I can be, I'm the one paying and I expect exceptional service. There are many GM dealerships in Denver, all with certified technicians, and I recommend everyone choose a different one for service; Len Lyall service is rude, unorganized, and seemingly could care less about your business. Awful!
