what should my max price be?

USAFstevo

I'm in the process of selling my M3 to buy a Z so Ive been doing some research to get my self prepared. What I'm looking for is a pearl white base+sport with a 6spd manual trans. I have multiple cars so I can wait as long as I need to before I get my Z so my plan is once i'm ready to buy talk to my dealer and tell them bottom line what car I want and for what price, I will show them my loan application has been approved for that amount from my bank and for them to call me when they have the car i'm looking for and I will close the deal that day. So my question is this and its an important one, what amount do I tell them is my max number? Thanks for the help everyone and I look forward to joining the Zcar family!
