so im 10,000km away from 100,000.i have had the x5 for 1 year(75,000 when i bought it)what im wondering is,is it worth it to do the 100,000km checks myself or just pay the price at the dealer?im a helicopter mechanic with full use of the hanger,so i have lots of room and time.it might actually be fun..the truck is a 2006 4.4i.thanks for any input..
