Bumper, The true cost to the GM dealer for the set of running boards(part #12499191) is $629.30. Most parts depts. want some profit above and beyond their cost. Some dealers are selling them in the $700 to $800 range which is a whole lot better than the $1,500 price you were quoted. Installing them is an easy 1 hr., or less, process. Go to the technical discussion site on this forum, go to page 2, Jan. 17, 2004, and you'll find more detailed info. on installing the boards. If you can't find a parts dept. that will work with you on the price then GMPartsDirect internet site has them for $755.16 delivered with all the necessary mounting hardware included. They are very reputable and I've had good luck with the purchases I've made from them. Hope this helps you in your endeavor to purchase a set of running borda!
