That's normal in China. People usually take 3 months or more to get license plate (registration) after purchase the car. In between, they just live with temporary license (paper license) which can be renewed on monthly base (?)
Anyone with knowledge of the purchase/registration process in China have an opinion on this:LA Times
If I read this article...and interpret it.....correctly...There is a big discrepancy between shipment numbers to china and registrations. If it is true that many people are holding off on finalizing their purchase waiting for the government incentives to be applied then we may have fewer 'deliveries'?
