Last I knew, NMAC was now extending all leases (on request) up to 4 years from in service date. If you have a high payment, Cwerdna's idea might be a good one, especially for a used Leaf with a warranty. If you have a low payment, I suggest you extend the lease and, if you want, get a one year warranty extension from...arrgh, I can't remember the name, but it's a Nissan dealership in CA that offers good prices on warranties. It's in the End of Lease Options topic.
2013 "Brilliant Silver" SV with Premium Package and no QC, and 2009 Vectrix VX-1 with 18 Leaf cells.
The most offensive, tasteless phrase in use here is "Pulled the trigger." I no longer respond to posts that use it.
