Newbie here starting my first A body

Welcome! I've used parts from AMD and have been very happy. Here's quarter skins. http://www.autometaldirect.com/body-components-quarter-panel-quarter-skins-c-23_145_146.html

They also have complete quarters for more money and the trunk extensions if needed. There's other suppliers out there to. Just Google. There can always be rot around the rear glass in the channel. Another area of concern can be under the cowl if it's full of leaves and been sitting in the rain. Sounds like it's been garaged for awhile but before that??? Pull up carpets and check the floors. If the wiper shaft seals leaked or the cowl leaked, you might find rust in the front floor pans.

If you pick it up, then the best thing to do when you begin to work on it is to post your questions in specific forums for more answers.

2k sounds like a reasonable price if it's solid. I looked for a couple years before I found one in great condition but I wasn't in a hurry so I could be picky.

Good luck.
