I have a used Yakima Super Joe Pro 3-bike trunk rack for sale. Originally $200 when I bought it in 2014. Has spent most of it's life in storage, and only used when I was transporting my bike. Normal wear and tear and completely functional. I used it on my old Honda Accord, but can be used on a variety of car types (including SUVs). Comes with an attached bottle opener for those days when you need a beer after a long ride.
This model is discontinued, but you can find information about the rack here: https://www.amazon.com/Yakima-SuperJoe-3-Bike-Trunk-Rack/dp/B004NT9N5W

$70. Can bring to Stanford's campus for pick up.
