We leased the Leaf for 36 months (15,000 miles/year). We put $2000 down and the payments are $445.23/month. I'll try to get a scan up of the numbers (there are a lot of them).
4 hours - I don't understand why. It wasn't like we were negotiating on price lol.. A little bit of time was with the reporter, a little bit getting the features explained to us (he had a checklist to go through), a little bit on the test drive, a little bit signing papers.. But we spent way too much time twiddling our thumbs. My wife actually left to try to go pick up some food and bring it back.
UPDATE: Below are the numbers. They are specific for my situation but I think they should be still be helpful to others
[*] MSRP=$35410 Price I paid=$34410
[*] $2000 down payment + $7500 credit = $9500 that is listed
[*] Residual of 44% of MSRP is based on 15k miles/year and 36 month lease
[*] The interest rate was 4.9% (Money factor of ~.00204)
