BMW 6 SERIES TCO (Total Cost Of Ownership)
TCO is the estimate of how much it will cost to own a car over a period of time. This takes into account expenses incurred on things like fuel, maintenance (repairs, service etc.), insurance, loan charges and loss in car value (depreciation) over the period of ownership.
The calculation here assumes a 5 year ownership period and an average interest rate of 12% p.a.
