Edmunds TCO shows the total cost of maintenance over 5 years for a BMW 5 series sedan as $3500. 5 years of Model S at $600 is on part with that. The Model S is a regular amount every year, the BMW is heavily back loaded to the last 2 years.
That would equate to 540 Euro each year for the BMW. I don't know about BMW's service pricing policy in the US, but that sounds horrendously expensive. As I said, I have to pay around 350 Euro for three years (ok, I only drive about 10,000 to 15,000 km a year), but that includes everything for the regular service intervals (oil, brakes, fluids, check-up, etc.). And as I said, my car is eight years old, so I would guess that newer BMWs should require even less maintenance.
By the way I didn't take tires into the equation because like someone else said, these would wear on any car. That said, most cars in Germany have 14 to 18 inch tires, with 15 to 17 inch being the standard, depending on the size of the vehicle. 19 inch like the Model S standard are already a rarity, and I have never seen any car with 21 inch tires, except SUVs perhaps. Even in the luxury sedan market here, 21 inch is the exception, definitely not the norm. Therefore 19 inch tires are not as easy to come by here as in the US, let alone 21 inch. Especially winter tyres. But ok, perhaps the European version of Model S will come with smaller tires, who knows. We will see.
