I removed the roof rack cross bars this morning on my '03 P5. I had only one tab break on the several parts I had to remove. My car has been garaged constantly, and that helped a lot. If I had been more patient, I may have avoided even breaking that one tab. I also replaced the deteriorating antenna with an Acura RDX one and filled the cross bars holes with the blanks that came with the car. The car now has an updated look, but still looks stock.
