Same deal here in NE Wisconsin. I will get $1,000 rebate on '07 I ordered if I take delivery (or can get a VIN) before 7/5/06. Dealer thought the Rebate might actually increase before then, depending on how sales are going.
It is usually better to take the rebates verses the 0% financing if u can get a low rate thru a credit union. I reseached it for about 3 weeks, rebates verses 0% and i came out ahead by quite a bit with the rebate. I got a awesome % at Pentagon Federal Credit Union (3.9), i had also refianced a 2000 Lincoln for the same rate. Good Luck
