Lexus of Silver Spring

I went to Darcars to lease a new ES 350. Everything went well untill I was called back to the dealership a week later to find out my deal did not go through. After waiting an hour to get my trade back I started to walk around the parking lot when I noticed my car with a dealer tag on it. I then observed my sales guy Mahummed taking the tag off whlie another guy took the window sticker off the side. When he drove my vehicle around it had 18240 on it. When I traded my vehicle in it had 17770 miles on it. Thats 470 miles more than when I dropped it off. So even though my deal was not approved somone was riding around in my car for 470 miles. And upon further inspection of my car I noticed the back window tint had been ripped. When I asked Muhammed what happened he said he don't know and left it at that. I am a salesman myself and the dealership I work for would have never let this happen. By far the worst experience ever
