Sorry, it's a very poor quality photo. This happens as people use there mobile photos to shoot a framed photo.
We were not able to contact Leonard Mermod who wrote: "All I know is that my Grandmother is behind the wheel in both pictures and that they were taken in England prior to August of 1912. My Grandfather had an automotive related business of some kind and lived in Chelsea at the time. I am speculating that these may be customers cars out for delivery or returned after repair."
Despite the ill quality of the photo we thought the car is so intriguing and the look of the young lady irrepeatable that we didn't want to hide the scene for you. Her roadster is very complete and has about every brass option you could get on a light car of the day. We presume it is around 1910. Also the shape of the bonnet and radiator is making us feel confident that we're looking at a Sizaire-Naudin runabout. Very close to this 1911-12 tourer version (Conam). In the same batch sent by Leonard.... was yet another photo of even worse quality. It's a big tourer and we do not even want to start a gamble. Over to you. Maybe a nice warming up for tomorrow's interesting quiz.
