I think by comparing cars, we can learn a lot more. For example maybe someone is thinking about buying a new Deville, they cannot decide between that or a new BMW 5 series. I cannot count how many times I've seen newbies post something like this. By discussing other cars IN THE LOUNGE, we can appreciate the ultimate experience of driving a Caddy. Where would Cadillac be if it were never compared to a Lincoln, or a Jaguar? Sure this is a forum for Caddies, but a lot of members have other luxury cars also, and personally, I like to know where I would stand if I buy a 2004 Deville, SRX or Seville. GM can also improve upon the brand by offering better or more useful options, technology in our cars, by comparing to other makes and models. IMO.
