Maybe it's a chick thing. But, I have to say I'm really annoyed when a manufacturer gives you keyless start but then does not give you keyless entry. Makes me think of those commercials that Ford is putting out lately. You can have a bed OR breakfast. You can have sweet OR sour chicken.
Like the actors in the advert conclude, AND is so much better.
So, while I'm mostly enjoying Mazda's all-new Mazda6, I'm a little bit rantful about the Sport model, which has only push-button start. As a female with a purse, that means you have to dig through the lipstick and wallet and pens and receipts and, well, and ... to find the key fob. Once you hit the unlock button and slide behind the wheel, you have no place to put the fob but back in your purse. Which then starts the whole fumble-through-the-purse process again when you need to lock the car. I see how not having keyless entry perhaps saves money. But the push-button start is a non sequitur once you've got your fob in your hand. I'd rather just use an old-fashioned key in the ignition if you're going to make me take the blasted thing out of my purse.
Base price for the Mazda6 is $20,880. To upgrade to a Grand Touring model -- that comes standard with push-button start AND advanced keyless entry, you're looking at $29,495. You can get advanced keyless on the Touring model ($24,495), but you have to add the Technology Package for an additional $2K, so you're looking at a price tag of $27,290.
