I am just going to overlook that reply. Definitely seemed uncharacteristic. Sorry you took the comment the wrong way. It was meant to be a little ribbing.
From my point of view, I know there are plenty of people out there that would like to sell their car's and their local market for a newpaper ad just won't cut it. EBay is a huge, easy, and well known place to look for cars. Given that, seeing a car sold by a 0 feedback person wouldn't initially turn me away. It is very probable that it is their first time using eBay for those reasons. What I look for is the story of why the car is being sold, accuracy of the description of the condition, pictures of the key areas, and details to the financial situtuation of the car (if it has a lien on it).
