Part six and the last day of our Christmas Quiz shows a well-known product from a coachbuilding company, started in 1880 by two brothers. In 1898 this coach was especially built as a present for a queen, and is still in use within that royal family (although this year it may have been for the last time, due to a long-term restoration). Car production started in 1899, with the first models on display in 1900. A few years later the company designed the world's first ever four-wheel drive car with a single engine. The final production year was 1926, although the name was revived post-war.
Now all you have to do is guess this make and the names of the makes we have shown during the past five days. A model name is not necessary. You can now send in your answers, but do so BEFORE Monday, January 4 2016. PLEASE click the "Add new comment' box and tell us the six makes.
From the participants with all answers correct, six names will be drawn at random. The solution to the quiz will be published on Wednesday January 6. All six winners will receive the famous PreWarCar T-shirt. Good luck and we hope you enjoyed this holiday season!
