Toyota has good quality in most of their vehicles so I was very disappointed that the center cap of their upgrade alloy wheel is cheap plastic with prongs that snap off easily. I did not realize this until the second time I took it to a garage to have the tires rotated. A couple of days later I noticed one of the caps was missing. I took off the other caps and saw the cheap construction - several prongs broken that hold the cap in place. When I checked with the dealer on replacement caps found out they are about $75 EACH!!!!
