my thoughts
Two sided sword,with out the internet we do not even get the chance to buy and sell at this level, but now the opportunities open up for the good and the bad folks to do "busniess", its sucks but true. I have been burned by internet scams and bad deals, but I have been burned by local speed shops too, so its still Buyer beware !!!!!!!
Do you home work, talk to the other party, get pictures, descriptions,honor payments, check them out on other sites, its not fool proof but it may help.....Good Luck !!!!!!!!!!!
