One evening I was told about a Ferrari Enzo in London and just as I arrived the owner returned and fired it up. He previously had 2 Enzos, this and another black one with the plate 2 XX; the other of which used to have a noisy exhaust but is now for sale in stock setup and this car seems to have had something done to make it a little louder although I couldn't tell you exactly what.
In the video you can see it start up before driving a few streets in central London.
