This is THE best trunk rack available. Fits most cars and SUVs (even with a spoiler) and is rust-proof since it's aluminum and poly plastic. Very easy to take on and off. 10 min to set up and then just a minute to remove and put back on. Folds very flat for storage in your truck or house, yet securely hold your road bike bike or MTB.

Ebay has some for $67 + tax and shipping and amazon has them for $153.
