Stunning pictures of classic cars in Paris

The classic car market is booming and there have been not one, but two, auctions of beautiful historic cars in Paris in the past week alone. We've already reported on the inaugural RM Auctions Paris sale, which saw nearly £15 million's worth of the world’s rarest and most exotic cars going under the hammer, including a Jaguar D-type that sold for more than £3 million.

Like the Smart ForTwo, the eScooter uses a steel and aluminum frame with interchangeable plastic body finishers.
