Food for thought...... Changing oil, filter and sparkplugs is very mundane and way below any qualified mechanic. So the only people doing it at the dealerships are the newbies, the ones fresh out of school or part timers or (you will laugh at this one but its true) the kids when it is take your kid to work day. Case in point I had a friend take his new ride in for its first service and he gets it back with the oil filter on so tight the outer case had a crease in it and the kicker, his new engine block with 3k Km's on it #3 cylinder with a heli-coil because the brain dead idiot cross threaded the spark plug with an impact gun. Moral of the story is do it yourself because you are the only one who will care that it is done right.
