When I started looking to buy my SRT6, I read several posts on this site. I, too, had the same questions. Read through these posts, and they will answer most of your questions. You must first answer the fundamental question: Will you be able to do some of the work, or will you have to rely on someone? I find the car easy to work on, and there's plenty of information on how to do it. As for parts, I purchase mine from Rock Auto, FCP Euro, and Autohaus. For any trim pieces, I go to eBay.
