First I would research the pricing on the net then compare it to what your dealership is asking. I would then look at what your max monthly payment can be and what's the max length of time you want to be paying on your loan. If what your asking is in resonable limits then stand your ground when negotiating. This is basically how I bought my Titan. Of course each time I stood my gound and the finance mngr kept saying "this is the best I can do" I would start to walk out. I believe I tried walking out 5 times before he agreed to my #'s.
