I didn't lease my vehicle as the purchase deal with trade in was better than I could get a lease for however if you are interested I would highly suggest contacting Sean Kass at Infiniti of Ann Arbor, MI. Sean is the General Manager and has a high volume of clients that lease vehicles. Sean ran through multiple options for lease plans for me and as soon as the time runs out on my new qx (have to get a new car every four years for work) I will be leasing one from him. Sean has lease plans to fit many different needs and can show you all of the different options for comparative purposes.
Good luck!!
