This I see as somewhat unfortunate for the following reason. ICE manufacturers basically option you to death...you think you are getting a great car but you have to get option after option. What that does is dramatically improve margins. What was nice about when I ordered was there were basically just a few options and you were done - this path is going down the more traditional ICE purchase path. Great for company and margins, not great for consumers.
Depends on the automaker.
When I got my 02 Nissan Maxima GXE, there were either no or virtually no options available on that trim. Despite it being the base trim, I had standard HID headlights, cruise control, power windows and locks, power driver's seat, trip computer, etc.
I looked into an Acura TL at the time, and there were a whopping 4 combinations possible: non-Type S and Type-S, with and without navigation system. ALL of them came w/leather, sunroof, heated memory power seats, CD changer, etc.
I just recently started leasing a '13 Leaf SV. There really aren't that many option choices. There are 3 trims: S, SV and SL. The only package on the lowest trim (S) is the charge package. On the mid-trim (SV), there are only 2 packages: LED + quick charge port, premium package. I got both. On the highest (SL), premium is the only package choice.
On the Prius, the trim levels go from Two to Five + Persona. Each of them really only has 0 or 1 package choice. Click Build under

From what I've heard, it's automakers like BMW and/or Mercedes who make many things optional.
