Jazz--"when you click on the links the whole thing 'jumps' a couple of px" -- you mean it shifts to the left slightly on certain pages? Isn't that just cause of the scrollbar which only appears on certain pages?
I'd been planning to leave the curve thing how it is, like it was supposed to be like that, but I'll try to smooth it out a bit -- something went wrong, and I lost my original psd file, so I've been kinda putting it off...the blue color's slightly off in that top left part, too -- something I wanted to see if anyone noticed besides me.
Gujumodel -- many, many thanks for the compliments

. About the contact us page, I'm working on the validation. The contact us form that's on the individual listings pages, however, was meant to be more of a "get more info about this vehicle" contact-type form, whereas the other is a general "email us about anything you want to". Any ideas on how to better convey that point?
It's great that the site loaded quickly -- I downgraded servers recently because I haven't had enough sites to justify the large one I had before. That this, with half the ram, on a 10 Mbit connection loads faster than most others on 100 Mbit connections, is awesome.

I'll try to make those changes first thing Monday morning when I get back to work.
*Many thanks to everyone who replied with advice/feedback!*
