Do what you are doing by getting as educated as you can on forums like this. Expect some problems, hold dealer accountable for fixing them, and then enjoy. That's how a huge majority of purchases go. Of course there are exceptions, but don't worry about that. If you are one of the unlucky ones, you will know soon enough and you can worry about it then.
