are online car insurance companies trustworthy/reliable?

i am looking at purchasing car insurance over the internet (belair direct or a company like such)
are the reliable, or is it a scam?
if i get into an accident does it cover me the same as a real insurance company?
and do you have any suggestions, as too which one might be better? or more reliable?

There are reputable insurance companies that will be cheaper to join via the web because it involves no work on their part.
You do your own joining. You could walk into a State farm office and it'll be one price or you could join State farm via a comparison site such as

However on the internet it's just as easy to join an insurance company that simply doesn't exist and when you realize of the rip off, you blame the net.
Well, don't blame the net, make sure you get insurance from a reputable company, one that you know has been coming through for years, be it from their office or from the net, as metioned, check with your state's insurance department to see if they are licensed to do business then go for the cheapest. period.
