BMW dealer charge you arm and leg for service but we get it done third party.
for example Xenon headlight bulb went my 7 series. i got a price from BMW and it was £110 then i phone a local part shop and they quoted £75 for one bulb. at last i got from ebay shipped from China £25 for Two bulbs.
i would say buying a car is not a big deal, its service and parts kill you.
7 series you see in the picture is for £5500. fully loaded, SAT NAV TV Phone, Heated memory Seats, 18" Alloys, nepa leather, harmon kardon speakers. there is to much to list.
this car is dady of motorway. around 250bhp
