Thanks guys ,it will be babied i can't help but spend money on cars it's an addiction .
What i was planning on doing is driving for a month and then take it to another BMW dealer for another report and if they find anything ,I can take it back and get it fixed up under the sales warranty (government regs over here all cars sold by dealers under 160k kms must come with 3 mnths full warranty )

took it for a run down a fairly corrugated dirt road on the test drive and couldn't pick up any noises ,.
Very impressed by the way it handled gravel road and tried an emergency stop in the gravel it was fantastic .
