Any idea why the Spark requires brake fluid changes every 30,000 miles? page 11-4 (314).My favorite page is the Maintenance Schedule table on page 11-5. As someone who has serviced gas engine vehicles since 1964, this table show how little maintenance is really needed. But it still has a gas engine to check.
Now here is the 2014 Chevy Spark EV Owner Manual:

And if you compare the same table on page 11-4 of this document with the Cadillac ELR (or the same for the Chevy Volt), you now see the the Spark EV is the simplest. This is the greatest benefit of electric vehicles - low maintenance cost!
