Keyless-go
Keyless start = push button start
Keyless go = keyless start + ability to lock/unlock doors without using key fob buttons, so fob can remain in pocket/purse
I think part of the confusion (and complaint) is that both are fairly standard on cars even 5+ years old. I had both on my 2011 and 2013 Infinitis, and it was standard. If I recall, my wife's 2010 Murano had both capabilities as well.
On the topic of remote start, I could not agree more with the people that stated here that it should be a function on the key fob. Having to use an app is "cool", but not really practical. It is fine if I am in my house and will be leaving in 5 minutes. But not nearly as useful when out and about and I just want to be able to click-and-start quickly. Not to mention, the Mercedes Me app is ssllllloooowwwwwwwwwwww.
