Unnecessary line

[tylercollier-devmtn]

In Step 3, this line is not needed:

this.buyCar = function(id) {
  carsSrvc.buyCar(id);
  this.cars = carsSrvc.cars; // <====== this one
}

I don't know Angular well but I'd imagine this line might not be a great idea:

this.cars = carsSrvc.cars

(there are actually 2 of that line; it's the same idea for both). You've got a reference to the service's data. The service should probably expose a getter to get a copy of the data. I realize this is not a production app but probably worth starting good habits. Thoughts?
