I although not my first choice I can understand the rationale of getting a light colored interior in this case.
Lake Havasu gets mega hot!!. From June to Sept the highs are over 100 degrees every day. Jump into a car with black leather when it's 120 degrees and you will never want black again.
The combo conforms to locale.
