If you like early military vehicles you might enjoy these clips of the classic Rolls Royce in action. Very much a symbol of imperial rule in the 20th century it was used in all sorts of places from the Middle East, to the General Strike of 1926 in the UK. If you go to the Tank Museum's article on their RRAC there is a hilarious picture of the Queen waving from one - worth a look honestly. Photo of replica at the Michael Collins centre. Film of one in New Zealand is at youtube.
If you want a model of one then for 1/72 scale the best place to start is the Reviresco range.
