How can I identify a pre-WW1 car?

I have a photograph of a pre-First World War car, complete with registration number. The car is being driven by my grandfather who was a chauffeur. I have tried many times to identify the car and its manufacturer, but no success. Can any one help?

Try the archivists at the National Motor Museum, Beaulieu. They make a charge for this service that goes back into supporting the museum.
