I had a saris rack for several years. I always hated it! I felt like my bike was going to fall off the car. It never did though. When I bought a new car I got a yakama rack and I like it much more.
I had a Saris rack when they first came out in the 90's. Absolutely LOVED it, and I was traveling to races twice a week with my bike on the roof, so I put a ton of miles on it.
