On the R/T, the compact spare doesn't take up any room. It's under the floor of the trunk with the battery. Yeah, I'd prefer a full size but that was not an option and it would take up trunk space. The Nav is a fun toy but not really necessary but we do like the U-connect for the phone. The radio is a personal thing, my ear is not good enough to tell the difference. Also, you should be able to negotiate something between invoice and MSRP, shop around.
