Upon review of the installation instructions, I decided to install the Stealth Hitch myself instead of having the dealer perform the work.
Perhaps not all people will take this approach. I am a mechanical engineer and used to doing mechanical maintenance and repair work.
The install was not complicated, the instructions are quite good, lacking only in suggestions for placing the electronic control module, how to run the cable through the body to the hitch and placing the wheel arch trim back onto the car.
The instructions say that the install will take 2.5 hours. This may well be true for somebody with experience. As I was taking my time and making sure all went well, the work took about twice as long. I did have an assistant to help me with removing the rear fascia, mounting the hitch bar and removing and replacing the interior panels.
The unit is solid, cleverly designed and beautifully constructed, the pieces fit perfectly without any adjustments. All the parts are packed individually in cardboard boxes for protection. The instructions are about 9 on a scale of 10, very good except as noted above. And best of all, the hitch is completely hidden from sight.
Overall, I am very pleased with the hitch and look forward to using it.
