So I am looking at getting a 2004 Toyota 4Runner Sport, upon inspection at Carmax, I noticed that the roof rack was missing and the holes were not plugged. They would not let me test drive the car because they noticed leaks near the rear side windows on both sides. Could this be from those holes? Where does the water from those holes go? Should this be an immediate red flag for possibly more damage? Any advice or anything else I can look for woule be great. Loving the site guys!
