Hmm. I am not sure I understand your statement:

"car1 is a reference to an object that behaves as the value of the "this" keyword."

First and formost this in JavaScript is used to denote what object owns a given item (function, variable, etc) as you have pointed out in the first part of your sentence but car1 is not a reference to an object that behaves like "this" (unless my understanding of the ECMA spec is incorrect) , it is an instance of your Car object thus pointing to that object.

Charlie, that was an excellent explination.
