Less times at the dealer = not having to worry about some yahoo driving your car, parking it too close to the next one, getting greasy fingerprints on your stuff.... fussy = me!
You also forgot these......
2003 Monte Carlo taken to dealer for free oil change. Had to have ground effects kit replaced because kid doing the oil change crushed them when he lifted the car.
2013 Malibu taken to dealer to have front headlight assembly replaced because it was leaking and filling with water. Had to have front end painted because of large scratch and chipped paint.
2014 SS Forgot to remove red spring shipping blocks.
All cars with less than 1000 miles on them. So you go right ahead and take it to the dealers as much as you want because they will take such good care of your expensive pride and joy.
As for me, I will do whatever I can to keep it away from the dealers. And on a plus side, if I am out in the garage my wife is happy knowing I am not out somewhere getting into trouble. Also she is standing by with the first aid kit. I tend to leave a little bit of myself with each job if you know what I mean.
