I’m not a big fan of bike racks that go on the trunk or roof of the car especially because the trunk racks can potentially ruin your paint and because the roof racks can be an eye sore. I found this Sea Sucker Bike Rack and was doubtful on how strong the suction cups were but after I did some research and tried it myself I was impressed. It also is safe on the paint and windows so you don’t mess up your paint and is easy to install and remove. Definitely recommend for any cyclists looking for a good rack.
