One thing not to do is keep accurate records of what you put in to your car

. I set up a spreadsheet and enter every receipt. While I am doing this for insurance purposes, when I see the accumulation in dollars it is depressing. My cure for the depression is to take a nice 2 hour drive down some winding rural roads. For me this is not an investment but a retirement benefit.
Have lots of fun with your new car. If it stops being fun then you are ready to move on to something else.
