Please post up some pics when you're able and thanks for the information, advice, and review!Followed StingEm's advice and ordered hitch from Etrailer. They shipped it for free and I received it in 3 business days. It arrived in good condition. Very happy with Etrailer.
My detailer recommended Auto Arts in Raleigh NC for the install. They did a fine job installing it and they did it in 2 working days. The price matched the estimated price of $422.50 plus tax.
Installing a hitch on a Kia Stinger is beyond the capabilities of your average hitch shop. It's much more complex than bolting a hitch to a pickup truck. Taking the rear bumper/fascia off a Stinger and carefully cutting it and then reinstalling it is best done by a body shop. Don't use a hitch shop to install a hitch on a Kia Stinger, take it to a good body shop or intelligent/skilled mechanic.
No modifications to the Draw Tite hitch were required for the install. It fit right out of the box. All the mounting hardware was included and used.
To me it was worth the $422.50 for a quality install with no problems. Highly recommend the Draw Tite hitch and Auto Arts in Raleigh.
