My 2006 GT (automatic) has push button start. Wasn't a factory option, had the dealer install it as an accessary. It's an option on 2011 if you get an automatic. It's great in the winter, I fire it up and wait to she heats up without every leaving the house. Someone did try to steal it at a gas staion once tho, of course the car shut off.
This is 'remote start' your talking about. Close but not the same.
I want to walk to the car and have it unlock itself.
I zit down and press a button to hear that sweet sound and go.
And no fiddling with key and keychains.
