+1 for all the push start comments.
And lets not forget that this also includes all the keyless entry features. The only time I need to touch the actual key is when I'm trying to find my car in a parking lot.
Not sure how much of a pain it would be to get all that stuff retrofitted in a FRS.
There's also:
- Heated mirrors
- Heated seats
- The whole climate control section of the center console
- Nice LED DRLs
- The boomerang headlights (I was gonna get Spec-D headlights if I went the FRS route, but having OEM makes me way happier)
- Courtesy lights in the doors
There was a recent thread about the BRZ Premium vs Limited. You can look there if you want more info:

(BRZ Premium is basically the same as the FRS in terms of creature comfort type features).
All the engine upgrades and FI kits will fit both.
The main difference in availability of aftermarket stuff is just cosmetic mods that depend on the front bumper.
