Engine Gasket Problem
 Purchased a lightly used 2002 X5 which runs well except When the coolant light came on,  $2000 dollars to replace gasket at 70K miles. Watch out BMW not taking responsibility for poor engineering. Found out this is a common problem with all of the 4.4L. BE CAREFUL!!  OIL LEAKS TOO. Buy it cheap or stay away - learn from my mistake!
