t web sizes, I really don't think you're ever going to be able to see a difference in image quality in a modern lens unless it has something smudged on it. I bet I could take two shots with identical settings, one with my 70-200 f/2.8 IS, and one with my 55-250 IS and you couldn't tell the difference. If you zoomed in to 100% then you probably could, but at 800pixels I doubt it.
The real difference with a high end lens is going to be the larger aperture and faster focus. But if you're taking static car shots and have them both stopped down to the same aperture, then they'll look nearly identical at web size.
Anyways, on to my new polarizer. This animation shows the effect that the circular polarizer can have depending on how you adjust it.
I found that trying to completely kill the reflections often left very "flat" feeling shots, so I actually chose ones that had a good balance of reflections, that showed of the lines of the car well. Here's a shot:
On a 3/4 shot I think you'd have to composite two images if you really wanted to kill all of the reflections. Sometime I think I'll have to give it a shot. I can certainly see times when you would want a perfectly clean image, with no glare at all.

A couple more from tonight:
This one was made from blending 10 photos with the circular polarizer rotated slightly for each one, in order to minimize reflections as much as possible. I really like how it turned out!
