I can only relate my experience working at a dealer and also special ordering cars for myself. It isn't always as simple as a small deposit you can get back or have that be all you lose. If it is you have little to worry about.
The last vehicle I special ordered was a new Chevy Silverado in 2007. I had to put down $1000 and if I didn't take it not only did I lose the deposit but I was going to be hit with more fees. I can't remember the exact total but it was pretty hefty though. When I worked at the Ford dealer they required a big deposit on special orders and you only got back a small part of it, or even none of it, if you didn't take the vehicle.
It will vary from dealer to dealer but just be sure of the terms of walking
away from a special order vehicle so you don't get burned. Sounds like you are determined to order and take delievry of a new Cherokee sight unseen though so I guess this is moot anyway.
As others have said let us know what you order and such.
