"We decided to pass on the annual service. The alignment had already been performed when we installed the new tires. System monitoring? We were just there in May when Tesla took care of a laundry list of items. Plus, they were already installing the firmware upgrade as part of the "Courtesy Inspection." Hardware upgrade? Any critical part should be (and was) covered under warranty. More on that later. So the only thing we were missing out on was the AC filters and the wiper blades, not worth $600." I love how they (and most) rationalize skipping this service (aka maintenance is for suckers). The more time a trained mechanic spends under, in, on and thinking about your car the better. Especially when it's a techno-feast such as the Model S.
