So here is how it goes, i bought a 1997 328ic with the sport package only 82K on it. I picked it up on friday the 25th and within 3 days the whole thing is just completely trashed. First of all it started with missing auxiliary fan on the water pump and that led to the expansion tank bursting and was leaking coolant that led to the engine overheating while the white smoke came out of my tailpipes which led to a blown head gasket! i now have learned that the engine is completely unrepairable. let me remind you that the car is only 4 days old any suggestions????
