First of welcome to the club and congratulations on your choice of BMW I got a 2003 4.6is. Now the bad news us if your car has done 80,000 plus miles it will defiantly need some or all bushes replacing just had mine done at a cost if abou £1,500 The good news is you will think your driving a new car . Bushes are there to protect more expensive parts so by leaving it you risk damage to them
