Ideal Terms for Plug-in Prius Lease Newbie

My apologies in advance for my detailed question as a lease newbie. It is my hope that the discussion thread here will be helpful to all Prius users considering a lease.

We have a 2008 Prius and have plans to add a Plug-In Prius (PIP) to the fold. My husband and I have decided that leasing makes sense. Working from home, most of the driving I do will be running errands in the neighborhood and likely consume no gas at all. Toyota is sweetening the deal by offering deep discounts this month of $5300 on top of a $800 dealer discount. Also, because the plug-in part of the technology is a recent development, a lease leaves us free to step up into a new, improved technology should that be something we want to do or we can simply buy the car. The current market residual value is slightly higher than the lease-end price.

I've read that Toyota Finance leases are among the best in the industry. So what components of the lease should I focus on to get the best deal? I want to drive off with a new Plug-in Prius with great terms, confident in knowing I have not been taken advantage of. I was feeling pretty good about completing signing a lease with a local dealership. While the salesman was aggressive, he provided a lot of useful information that led my husband and I to decide to go with leasing a new Prius Plug-in, when we previously were considering buying a used Prius. He broke out the offer on paper, and showed different monthly rates were we to put different amounts down. We eventually indicated that while we were going to do research, the 3-year, 12-month, no down deal seemed the way to go.

I explained clearly that I would not lease on the spot, that my husband and I needed to discuss and research the matter this weekend. I explained I make it a practice to do very granular research and the way to close a deal would be to provide us with the level of detail required to run the numbers and analyze the fine print. The salesman pressed us to put down a $2k deposit, refundable (he wrote that on the form), to hold the 1 remaining plug-in, which we agreed to do. He then assembled an informational folder to take with us. However, when I opened it at home, none of the numbers had made it into the folder. It seems a red flag. The dealership does have an A+ rating with the BBB unlike another one just a mile from where we live, which has a horrible reputation and an F with the BBB. Consequently, I suspect the failure to include the number is more a tactical move to prevent us from shopping the deal as well as enable them to hold the advantage in the negotiation when we return and get hit cold by numbers we hadn't had the chance to review on our own.

Working from memory, the numbers/deal we were offered for the basic plug-in were as follows for a 3 year lease, no down payment, with 12,000 miles:

List: ~$32,000-$33,000
Dealer discount: ~$800
Toyota discount: ~$5300
Lease-end purchase: ~$16,900
Monthly cost: $356
Money Factor: ? (The finance guy stated its "something like .001. When I do the math, that coverts to 2.4% interest)
Capitalized Cost: ?

I look forward to your thoughts on negotiating the best leasing deal. What number seems reasonable for capitalized cost? The text above suggests that's the piece that's negotiable.

Are there any other variables worth focusing on in the negotiation? My sense is that some things that might be negotiable elsewhere might be locked in by Toyota Finance. For instance, is the money factor locked in by Toyota Finance? I know they will run our credit (which is excellent). Is that something we should do in advance either to negotiate the money factor or verify that the math is correct?

The dealer offered to "throw in" the wear and tear guarantee at his cost -- $14 monthly -- which he said he markets for $24 a month. Does that sound like a good deal and is that guarantee something you'd recommend? Perhaps I could press for them throwing it in for free.

I also welcome your general advice on length of term, annual miles, and whether it makes sense to put $ down to reduce monthly cost . . .

Last, I welcome your thinking on whether you'd do business with the dealership given the disappearing numbers. I have sent an email to the salesman requesting the numbers in writing, stressing that was the path to closing the deal. We will be returning tomorrow to either complete the lease negotiation or walk away.

Many thanks!
