2018 options for XM ... radio price is steep.
 

I have been surfing the new 2018 Mustangs, and one thing I really
like about the one I have ... (and the previous cars ...) The
XM radio. ((XM ain't what it used to be, but its paid for :)

The sticker price (Note: I did get it at one year old used)
compared to comparable current is $4,500 more:


2011 ....
$29,580 V6 Premium,
comfort package (heated power seats)
performance package


2018 ....
$34,090, Ecoboost Premium
(includes heated seats I think)
performance package

That is an added $4,500 over the years ... (only 13%?) Before
wheeling and dealing, and applicable rebates ...


So, I was thinking base not premium, plus two options ...

$31,075 Ecoboost base
101A Sync3 (XM/Sirius $2000!)
EcoBoost Perf. Package (of course)

... to knock off $3,015.

So ... that radio is a LOT. It costs extra to stream the XM/Sirius,
so need the real radio.

Would it be a good idea to skip the 101A, and wait for a used
setup? Or - older threads out there seem to indicate you can maybe
add some capability (thing, plus antenna) to get to XM? Aftermarket?


Thanks!
