Lease Pricing on 2006 Hummer H3

[grims34]

Hi everyone, I am looking to purchase a new Hummer H3 with an MSRP of $38,480. I will be trading in my 2002 M3 coupe which I looked up on NADA as having a trade-in value of $37,380. Retail value of $42,000. I still owe $30,412 on the M3. I was wondering if the dealer gives me close to the NADA.com price, what should I expect as a lease rate for 15,000 miles a year and 48 months.
