There is something special about the smells associated with cars - and not just that new car smell, either. I make no pretense of being an expert on what makes a car run or improves fuel efficiency. I do however, know what I like and am presented with opportunities to create interesting stories that intrigue and provoke thought. And those smells? Leather interiors; new tires; gasoline; even malfunctioning catalytic converters. All part of automotive DNA. So for me, it's all about the sum of the parts. Will this vehicle get me from A to B; will I be comfortable; will the drive be entertaining; and, most important of all, how easily and intuitively can I link my smartphone via Bluetooth?
