I have an extremely hard time believing that. I've had experience with Xtreme Jeep, and they were extremely knowledgable; more so then me and I consider myself well versed when it comes to Jeeps. Even people without Jeep experience knows what the models are..
My recommendation: Buy online from a reputable dealer, and bring it to a shop to install. I recommend Xtreme Jeep for the installation.
