Any great car has at least one forum on the Internet devoted to talking about nothing but that car. What's great about these forums is that frequent visitors build up a great and helpful community, and are usually more than happy to share information -- including detailed photos of maintenance or modifications they've undertaken with their cars. Usually, everything from quirks regarding regular maintenance issues like oil and sparkplug changes to fine-tuning suspension setups is covered on one of these forums. You can learn about what ECU chips owners like for a particular model, as well as why they like them. You can spend days learning about tire choices for various conditions, depending on what you want to do with your car. You can also ask questions and get helpful answers, as long as you make sure that question hasn't already been answered before. A quick forum search for variations on your question will save you from the path of potential facepalms, public shaming, and rage-quitting.
