IMO the big issue here is forcing the service plan to get the software updates. I am comparing this to other electronics products like the Iphone or Computers, they give you software updates free. Software updates for the Model S and future Tesla Cars should be free, customers will demand this, a precedent has already been set.
Now for the actual maintenance charges - have any of you reviewed Edmunds True Cost of Ownership calculator, here:
True Cost to Own (TCO) Calculator on Edmunds.com
Let's look at Model S competitors per the Edmunds TCO Calc using the Maintenance line costs:
Audi A7
Year 1 $432
Year 2 $547
Year 3 $1,015
Year 4 $2,736
Total = $4,730 ($1,182 / year)
BMW 7 Series
Year 1 $0
Year 2 $0
Year 3 $0
Year 4 $4,100
Total = $4,100 ($1,025 / year)
Porsche Panamera
Year 1 $46
Year 2 $831
Year 3 $717
Year 4 $3,254
Total = $4,848 ($1,212 / year)
Average cost per year for these three cars is $1,139. Model S is $600 per year or nearly 50% less. I do not see a problem with their plan.
