Re showing ads based upon sites visited, I have never been on auto manufacturers web sites except Ford. Last Jeep I drove was when I was 16, learning to drive in a 1948 Willys. The last Dodge I drove was a company car, about 30 years ago. Dunno what Google thinks, but ad serving is a strange business. No matter. I use an Android tablet 95% of the time (rarely use the Win7 laptop anymore), so AdBlock isn't an option. I just thought the choice of ads was amusing.
