Always* start with the PET if Porsche, or manufacturer parts diagram if other brand. Depending on the brand, these can be a huge pain to dig up. I don't understand why they don't all make it as easy as Porsche does. If you can download a PDF of your vehicle's factory service manual, that often has the parts diagrams. If not, have fun Googling. LexusSouthAtlantaParts.com is pretty good for Lexus diagrams, for example, but even that is sooo much clunkier than the PET.
Once I have a part number, I usually plug it into eBay, Amazon, and Google Shopping. Of course, depending on the part, I can call the local dealership with the part number and get their pricing, too.
*Except brake pads. I usually like to pick the manufacturer and compound, then use their part number to search for retailers.
In parallel to the part number search, I look up almost everything on RockAuto as well. It's the only website that works better with its own organization system than with factory part numbers. You can plug in a factory part number on their search, and it works...maybe 20% of the time. You're better off just working your way down the tree.
