Actually 7 days and 23 hours, but who's counting. They told me when I scheduled that it was not the tech's first conversion, but admitted when I dropped it off that it was his first time, not at the "school" where he did one under supervision. Not sure why they hadn't done their demo if he needed practice but at least I had it to drive for the whole time. To be fair, they said the battery enhancement was complete after three days but they didn't realize they were missing a special tool necessary for the coolant sensor install. That took 3 business days plus the weekend to arrive (Thursday to Monday). After reading on this blog that a shop an hour away did one in a day and a half, I was a little surprised.
