internet car scams

ok guys i am in the market for a new used car. i got on craigslist and i have found several listings that i think may be scams and i was wondering if i gave you all some of the email addresses if you could look up the ip address and furthermore maybe find me a location of the computer used to access that email. if you could do this for me that would be great. i can not afford to lose $3000. thanks guys

and the only reason i listed in here is because it said security, so if this is in the wrong place please let me know and ill move it or a mod can. ok thanks

ok guys nevermind and thank you i have verified that they are scams thank you
