Compared to the standard 6-Series, the M6 is pricey when new especially when you consider it's as expensive as top end Porsche 911s and the Aston Martin V8 Vantage. A new car will still take a sizeable depreciation in in the first 12 months while insurance group 20 and 19mpg add to the costs, but if you have to ask . . .

Vehicle excise duty (VED) varies according to the CO2 emissions and the fuel type of the vehicle. For cars registered before 01 March 2001 it is based on engine size. For cars registered on or after 01 March 2001 the VED or road tax is based on the car's CO2 emissions.
The M6 returns just 19mpg on average, so it's no surprise that it scores so lowly on the eco front. With emissions of 362g/km CO2 it scores similarly to other supercars from Aston Martin, Audi and Porsche but fortunately, these sorts of cars tend to be driven less per year than the average family car.
Highest and lowest CO2 bands
|Engine||CO2 emissions||VED band||Road tax (12 months)|
|5.0 V10 Petrol||342 g/km (Min)||M||£515|
|5.0 V10 Petrol||352 g/km (Max)||M||£515|
There's a lot of technology in the M6, as well as a high performance V10 engine, but BMW generally has an impressive record in terms of reliability and durability.
