Yes, that was very perceptive of you on the sales tax...that's one advantage of the Volt approach, at least here in California...effectively cuts the monthly payments by around $20. Some states it doesn't help since, I am told, even on leases sales tax is on the entire amount.
Yes, all three cars leased, all on zero driveaways. I think leases are the way to go for EV's. Ford is exceptionally easy to deal with in that they offer leases up to 19,500 miles per year, and I am told they even allow you to pre-buy additional miles beyond that which are refundable if not used. Chevy was inflexible, 15,000 being the highest but plenty for me since I use the FFE for the long daily commute (80-100 miles daily). Only better deal was the one my friends got on a Rav-4 EV...unlimited miles. They've gone 15,000 miles in 7 months.
Since I didn't buy the extra miles, I know I'm done with this car at 58,500. At my present burn rate, I will hit this a few months before the lease ends. I don't know whether to shift some of the miles over to the Volts to get it to last right up to 36 months, or whether to turn it in whenever I hit the miles. I presume I will need to pay off the remaining payments, but at least I will save insurance for a few months. Still don't have this one worked out.
I like the way leases deal with the $7500 in that it's for-sure and happens right away.
I was at first suspicious of the "zero driveaway" talk at the Ford dealer, figured they were going to somehow ding me for tax, license, something.... The sales manager resolved my concern by saying, "You give me exactly zero dollars and I give you the keys. You write Ford 35 monthly payments and give me back the keys". They were equally straightforward at Chevy and Toyota.
