For example, if you probe their production web site, you'll see their app makes requests to
http://www.subaru.com/rawdata/imprezawrxsti.html
to get msrp. In this mock up we see that it's requesting data for
https://proj4.boxer.subaru.com/rawdata/brzlimited.html
I tried switching that to
http://www.subaru.com/rawdata/brzlimited.html
but no love. They may not yet have the production software deployed.
