As I said earlier in the thread, my wife had a pre-facelift W213 with keyless start but no KG. Another car from Germany to prove a keyless start car exists without KG: WDD2132041A506409.
Also if we were talking about US cars, see the website superswiss referred, it states:
Mercedes-Benz KEYLESS GO®: Essentially an upgraded version of KEYLESS-START®, Mercedes-Benz KEYLESS GO® allows you to start your ride by pressing the brake pedal and dash-mounted button as well as lock and unlock your Mercedes-Benz vehicle with a tap on any door handle by sensing the SmartKey in your pocket or purse. This feature is standard on more tech-savvy models, like the Mercedes-Benz GLE Coupe and S-Class Coupe, and optional on any new Mercedes-Benz vehicle.
Meaning at least current models (in the US) have keyless start if they have KG. The web page also says current models have keyless start as a standard feature. At least it has not been any current Mercedes model loaner that you've had with KG but no keyless start.
Talking about older models, I wonder if this is all about an operator error. The first generation keyless start cars had a traditional looking ignition slot but accepted a small plastic cap replacing the key. If the small plastic cap was removed from a loaner, the car would have working keyless entry but no keyless start.

I though superswiss said earlier that a fourth option exists: a car with keyless start but no KG. Can you get in agreement about the list.
