I was looking around at some domains and found a few that could be used.
www.jwmotoworld.net
www.jwbuzz.net
www.jabbamotoworld.net
www.automoton.net
www.automotorfan.net
www.worldmotoportal.net
www.topautoportal.net
Thats just a few, i like the moto and auto sound, (if you haven't guessed) but I am a fan of JabbasWorld but i know how it is with you name on a site, well atleast dealing with name change.
