Obscene parts price of the year! How about this 09 Mercedes S550 rear body panel rivets. The rear body components on the car are aluminum, the frame members and outer quarter panels are steel. So to mate the two together they are glued and riveted. The glue is about $500, ok, that is pretty nuts being we get cartridges of a VERY similar (probably exactly the same) product for about $50. But ok, then it comes to the rivets, folks there are about 100 of these rivets used to install the rear body panel which we will be doing on this car. The cost of the rivets (they are about a 1/4 inch by 1/4 inch long) are $17.95 EACH!
