Believe me. Go to the national gallery or any other large collection of paintings and you can tell the difference between a run-of-the-mill artist and some of the old masters. Their work has a little something special about it. As punky says, it's also a part of history and you also have the name that goes with it. Why do people pay hundreds of thousands of pounds more for a Rolls Royce/Bentley/Aston Martin/Ferrari? They're only cars aren't they. Surely a 25 year old Nissan bluebird is just as good!
