Hmm, depends on how much you put down, the money factor, residual, interest rate. I'm guessing on a 24 mo lease your are not going to get a great deal. My guess with $2-$3k down it will be $700-$800/mo. for 24 (if not more). 36 would probably be more in line.
Why don't you just buy it--interest rates are darn near free? I put $5K down and got 3% interest rate for 60 months came to about $570/month.
