One question remains, though.
2" receiver is described as "removable".
The accessory hitch is described as "factory installed".
The option says "when not installed", but that text is listed as part of the option and then below the break they reiterate "factory installed" again.
"Factory installed" implies to me something that isn't easily removable, but "when not installed" implies that it can be uninstalled.
Is this a case of:
- base car has diffuser permanently installed
- simple (low cost or free) option to permanently install a very simple bolt-on 1.25" hitch
- more expensive option to include a full tow package which includes a more complicated removable 2" hitch (possibly with a diffuser that can be used when removed)
Or, is it a case of:
- base car has diffuser in place of hitch, can be removed for either hitch
- low cost or free option to include a 1.25" removable hitch
- more expensive option to include full tow package with 2" removable hitch
Most cars that have after-market hitches available, the hitch bolts onto 3 or 4 parts of the frame and you leave it on permanently. It could be unbolted, but it is too much of a hassle to add and remove as you need it. Many of them come as "hidden hitches" which basically are recessed back from the bumper so they aren't as visible when not in use - the intention being that they can be left installed all the time and remain discreet, but still installed, when not in use. Note that the hidden hitches don't always work with all accessories since many are manufactured for decent clearance only if the receiver opening is even with the back of the vehicle. This has actually impacted me in my search for a bike rack because I originally opted for a hidden-style hitch as the rack I originally purchased had a long tongue, but later I wanted a nicer rack and only a couple came with a tongue long enough to clear my bumper when folded.
The X obviously has the capability for a removable hitch, based on the description of the tow package, but the mechanism for that may not be simple or cheap and so they may only bother with it if you opt for the full tow package. Does the description of the base accessory sound like the 1.25" receiver is a bolt-on "not really removable" hitch or not? My gut feel is "not", but I may be reading too much into it.
Also, the picture of the 1.25" hitch does not look as recessed as most of the hidden hitches that I've seen, which might lead some to prefer a removable hitch for looks when it isn't in use.
