They won't usually offer 0% APR unless there's a current special for 0% APR.
-They don't "hike" up the price with 0% APR. They just usually will not honor any rebates AND 0% financing. You usually choose one or the other.
-So if 0% isn't offered as a promotion, you probably aren't going to get an APR that low.
-If it is offered, then best is to bargan the best price you can and still get the 0% APR.
-If 0% and rebates are offered, it's your choice.....maybe just take the rebates and get your own financing..etc.
