Two owners including myself! Low mileage for the year. Oil service every year regardless of usage using bmw standard oil only and filter. FBMWSH. All pads and discs replaced in the year. Not used for commuting to work so low mileage per year. 4.5 to 5.5 mm thread all round on tyres. M4 competition gloss black wheels, msport brembo discs and Mperformance brakes, bmw Mperformance full carbon fibre body kit, launch control, harman kardon logic 7 surround system, neck scarf warmer in addition to the heated memory seats. Stunning looking convertible. Economically good on fuel for the size of the engine unless you want to unleash the power! Loads of money spent to maintain this lovely bmw xdrive. Forced to sell due to needing a family car. Will be sad to see it go!
