Nightmarish Usability (revised) - www.carsales.com.au doing it right!

I just wanted to reflect on my experience with carsguide.com.au with an example from www.carsales.com.au:

- Browsing issue is sorted by carsales.com.au disabling the browser navigation button on their photo gallery window;
- they have, however, maintained individual URLs for gallery pages, which is completely fine as long as visitors can close the window when they're done browsing the images (see below in red):

I am sure carsales.com.au will want to ultimately host banner ads in the future in these "sticky pages" (and rightfully so...), but it will be interesting to see how this affects overall usability.  I hope they find a way to do it with minimal frustration on end-users and maintain their "Australia's No. 1 because it WORKS!" slogan in reality :)

Thanks www.carsales.com.au, will be using your site from now on!
