I bought my IS250 from Lexus of Las Vegas. When I first went in there, the sales person wasn't willing to give me any kind of a deal on a Demo IS250 with 500 miles. <_< So I called the internet department and I got an awesome deal on a 250 with 11 miles. He also gave me free window tint, leather key fob holders, keychains, a cargo net for the trunk, and a gift certificate to Trevi. I spent about an hour @ the dealership, so overall my experience with the internet department was great...
Hope this helps!
