I have the same upgrades in mind. Ford uses a computerized service manual( I forget the name), but they are usually available on ebay or similar websites for pretty cheap.
According to the latest bulletin
"until further notice, stock hybrid orders will not be selected for scheduling."
Who knows how long further notice will be
I'm happy with the price of the XL and standard features. All I will be adding aftermarket is cruise control for me and heated seats for the wife. To get those options from ford would mean a $4000 upgrade to the XLT luxury package
