That "disposable" mentality is the same kind of thing that got us all into the current financial crisis -- you sound like you have a lot more disposable income than I have, but what will you do when it runs out?
"Drive it like you stole it" makes for a neat bumper sticker, but "Drive it like you OWN it" is a much better creed to live by in the long run. Even in the world of motorsports, winners and losers can often be separated by those who know how to take care of their machinery and bring it home to victory, and those who obliviously abuse it until it dies (which usually results in a premature retirement from the race and a "DNF" in the win column).
Good luck figuring this one out.
