I talked to my bro & sister in-law tonight: I'll use their approx. 3 year-old Montana instead of my sister's Sienna (logistics easier). Not sure what the Pontiac's Cd is, but I'm guessing it's higher than the Sienna. I do know I'll have to remove the OEM roof racks to do the test. Fortunately the torx screws are on the outside, so it shouldn't be too hard to do.
