Welcome Joe. Glad to hear you're happy with the Prius. Don't be too hard on diesels, overall they are much better for the environment in the long run, I feel the emissions scandal is unfairly tarnishing diesels, especially in the US where stories tend to get twisted, dramatised and exsadurated somewhat!
Remember not only do diesels save fuel, they slash C02 emissions dramatically, and virtually eliminate other emissions like hydrocarbons and carbon monoxide. As you probably know now, modern diesels have also cut N0X emissions by up to 90%, so all these recent "issues" have already been resolved.
Enjoy the hybrid
