Bike rack

Hi to all.

Do any of you know if it would cause problems to use a bike rack similar to the one pictured in the attachment. It uses straps that attach in the space between the rear window and the trunk, to the side of the trunk and under the car.

I have used it on different cars without problems but I am a little worried of using it on the EOS because of the way the trunk works. Would it be too heavy once two bikes are mounted on it when you take into account that the trunk of the EOS also opens backwards.

Thank you for your help.
