Via YouTube member Drake Mumford we came across the following tuned BMW E60 M5. The owner calls his car “Gunther”. It is fitted with some ridiculous modifications, many done to the engine, many done to the interior (racing seats, half roll cage, etc.), but the best mod is the exhaust.
Two videos below show the luxury power saloon with its wide arches hit the streets somewhere in the US. The difference between the two videos is only half a year, and includes some design differences. Underneath the new full body wrap the same car is still visible.
