I was wondering if I could get some opinions about these "Matrix" sites that people are advertising on Ebay. I was curious about an auction on Ebay so I paid the 99 cents to get the information and check it out. The auction advertised a link where you could purchase in-dash dvd players for $100 and stuff like that.
I will do some research myself, let me know what you guys think about it.

its crap.... stay away from them.

It's the same thing like the free Ipod website thing. You need 5 or 6 people to bid on it under you before you win it or what not. Matrix is a trick to make you think you would get it, but most times, you won't.
