Hi — First off, I'm sure this question has been asked a zillion times before, but I searched and couldn't find anything definitive.
I just bought a 2013 Lexus RX 350. It's my first car (other than the '71 Dodge Dart my grandfather gave me when I was a teen) and I was wondering what best practices are in terms of maintenance. How often should I take it in to get a check up? What can/should I do myself? etc. I'm pretty clueless when it comes to cars (though I'm totally willing to put some work in to get a clue now that I have a car), so any tips would be very much appreciated.
