Drudge, call up your local wrecking yard and have them do a search for the parts you are after. They have a national database that they can look on and see what parts are where. Can't garantee the price you will be quoted as the price is set by the yard holding the parts. Then of course the local yard is going to want to make some profit too.

Of note, you can get the metal part of the door brand new from jaguar for $561 plus S&H. Now, you would end up reusing the glass, interior trim, and wiring harness though. Plus there would be the price of painting the door too. But, the paint price was probably already being figured into your pricing. The rear door is cheaper at $536. Check out http://www.jaguarparts.com and then look up the "front door" and "rear door". From there, you can see what all the door components would cost should you not be able to find them elsewhere. This site is a Jag dealership out of Cleveland Ohio. I have used them and highly recommend them. They will make sure you get what you need.
