It is so convenient. I absolutely love it. We had a Mercedes Electric which I was very happy with. The range was the only real problem and having to make semi-regular trips up to KC for my wife's doctors. The plug-in hybrid is ideal for us. Electric for most of our driving but hybrid with 86 MPG rating for the highway trips up to KC.
You just cannot beat plugging in at your house overnight. The Lexus and the Mercedes use the exact same charger. One has the Benz logo the other Lexus

. The Lexus lets you schedule when to charge. So far, it seems like the absolute ideal car.
