I have a 2011 Buick Enclave with factory installed side and cross rails. Will the 1700 fit and will the back hatch open with it on?

Hey Bill,

Thanks for the question. I checked with Thule and found that the Thule Ascent 1700 Cargo Box will fit on your 2011 Buick Enclave with factory crossbars.

Opening the back hatch will depend on whether you are able to move the factory crossbars back and forth or not. If so, then you'll probably be able to adjust them accordingly. If not, then you might be able to open it still, but I can't make any promises.

What will I need to attach this to my '99 VW Jetta or my '05 Mercury Sable? Is it universal?
