Wasn't sure what section was appropriate, so just putting here. I'm in the process of purchasing a 2014 XLE with 20k miles. Had it transferred from Tallahassee and just got to see it in person and drive it. Looks great, drives great, and feels great. One thing I noticed though was looking around the engine and compartment, there is a white sort of oxidation residue all over the aluminum parts (head, etc.). Wondered if anyone else has seen this or what it might be from. Not sure if the engine was sprayed with some sort of treatment for the black bits that didn't agree with the aluminum or what. Don't have pics yet, but will post some as soon as I take them.
