Question for my American friends. If you go to a Toyota dealership and order a Lexus part, can they get it for you? And I don't mean a shared part, but suppose a part that is unique to a Lexus, like an interior piece as an example. I ask because here, a Toyota dealer can only get some parts for a Lexus but not all. I don't know where they draw the line, but according to a dealer here, many Lexus specific parts they are no able to order.
An example is a cabin filter, the Toyota dealer here said I have to go to Lexus to get one for my car because it is not a part used in any Toyota.
As for the ES330, the drivetrain is largely the same as a Camry. Parts are readily available, and there is no reason a Toyota dealership would not be able to handle any maintenance or repairs on the car, providing they can indeed source Lexus parts.
