Is this the same dealership from which you got the car? While you lease the car 3 yrs ago, I think you might want to try getting a quote from another source. Here are (lots of) ideas:
Was your total lease cost ~$49K (incl down payment and the warranty upgrade)? An internet search indicates that base MSRP for your model was ~$60K. Assuming this is correct, I think you either chose a model that doesn’t (didn’) lease well and/or were horribly ripped off by the dealership.
I would suggest taking some time to read through Leasing 101 to learn the basic concepts involved in leasing and consider working w/ one of the highly-rated California brokers in the Marketplace her (there are also broker/dealer reviews in another section), since 2 months is not a lot of time to learn this info.
