McLaren F1, much worthy than a mansion outside London?

In 1994 if you were willing to spend 650.000 pounds on a car, the current equivalent of 1.000.000 euro, you would be considered crazy. If you were willing to spend the same amount of money on a mansion outside London you would be considered an investor.
It looks like things changed a little over the last 20 years, and those who would have bought the one million car would have made a fortune today. Of course, if the car had been a McLaren F1.
UK-based real estate services provider Savills has released a video that compares how the prices of the McLaren F1 and of a mansion near London have evolved in two decades. Both increased their value, but it is important by how much. You will be surprised to find out the difference.
