I am getting traffic at carbuzzard.com from a site racecarreview.org. What's odd about that? There are no links on racecarreview, and if you visit the site, you'll see that there's not even any there there. I'm not sure why the page is there, other than the google adwords ads, but I can't believe that page gets any traffic. So why do I keep getting traffic from that site? Something about it just creeps me out.
If the traffic is comming from http://racecarreview.org/ and not a sub page you must be seeing adsense referrals, if you currently got a campaign running.
i think those site is making referrer spam to your site. it's better to block that web site from your cpanel
