Just a curious observation. I have a 13 X3 28i with just shy of 5K miles. It is wonderful. I recently noticed that it takes what seems to be a long time for the engine to warm up. I thought maybe this was just my car with the low miles, but last week I had a 12 328 loaner that exhibited the same characteristics. My C300 doesn't take anytime for the engine to warmup.
Just curious if this is normal to this engine.
