AutoNation Volkswagen Las Vegas

My wife and I went to this Dealership to purchase a used 2016 Volkswagen Tiguan. We met with a "nice" salesman. We looked car over and found a bolt laying on top of transmission that was "forgotten to be installed". We were assured that this is a no Issue item due to fact that nothing was noted on car fax and car would have 2 year bumper to bumper warranty. There were two areas of small damage to car and we told sales person that we had a cash deal if they would be fixed. After he went to his manager they agreed to fix the car. we put 5000 dollars down and would pay almost 14000 dollars upon pickup. 4 days later we were called ,car was ready. Upon inspection areas discussed were brushed painted.and I was told That they had fixed them. The salesman and sales manager told me that this is the way they "fix" cars for resale. I was then told I needed to understand. I have purchased dozens of cars in my life and never have been treated this way. When you tell a customer you are going to "fix the issues" a paint brush on a scratch and dents are not a fix for a delership. We were told that we could take it or leave it. I chose to leave it. $20000.00 and a upset customer does not mean much to this dealer.
