Window tinting averages 250 depending on how dark you go.
15k "tune up" is nothing more than check this, that and the other thing over there, lube the doors, rotate tires, check brake lines, steering and suspension components, oil change, diff fluid replacement and filter replacement, both engine and cabin.
Lifetime oil changes? What kind of oil are they using? Is the "free" just covering the cost of conventional oil? Is it dependent on you going to just that dealer or is it effective at another Subaru dealer if you are out of town when its due? Lifetime literally, or lifetime upto x? Premium oil changes average $45 for conventional oils and upto 110 for synthetics. So, if you travel 12k a year, that's roughly 2.5 oil changes a year with synthetic and 4 with conventional.
Do the math and read the fine prints. A lot of the maintenance items at the dealer are free at places like Jiffy Lube and the like.
