The 2 X5 I saw yesterday on I-90

[LeiZ]

The first one I saw was a white E53 on I-291, the same as mine, passed me over on the left lane. The driver was quite nice that we waved hands to each other and then he drived away. It was a 4.4i I'm pretty sure.

The second one I saw was on I-90 between Exit 7 and Exit 8. The car was driving west bound, and HUGE WHITE SMOKE was following it. I'm pretty sure the driver didn't notice that, because the smoke was almost 1 mile long. It was a white one as well, but can't tell what engine model it has.

Hope the second car won't get too much damage.

Just curious, white smoke? head gasket?

Usually. Esp if it's doing it on the highway. Typically by the time most folks jump on the highway the car is warm enough that most condensation that appears as white smoke has burned off.
