My Mom couldn't understand why I would buy a diesel until she rode in my CRD. She said, "I thought this was a diesel? It doesn't make that clack-clack sound, it doesn't smoke, and it doesn't stink."
Unfortunately, most people are like my Mom. They still remember the diesel crap from the 70's and early 80's. We had a diesel van when I was a kid. Ran great, but it was SLOW, noisy, smokey, and stinky.
I'm actually a bit saddened by the CRD. I like the diesel sound, and I actually like the smell. I remember getting sick as a dog when I was a kid from smelling diesel fuel straight from the can. I still love the smell though.
