I saw a lot of flak about this website, calling it a scam etc, waste of money, etc etc. Non the less I needed to register my car over the weekend so I could visit some buds. The standard DMV site wouldn't allow me to register my car because it was past the renewal date. I would have to wait until Monday to get my car registered.
I decided to give this website a shot and see if they could get me registered before Monday. Sure enough with an hour or two they provided me the a pdf of my updated registration. So yes, they do charge for a service, and yes you can do it free online at the DMV site if your within your renewal deadline date... but if you were in a similar situation then this website is far from a scam. Food for thought.
