It really depends on what is most important to you...
Diesel
Pros - fantastic range and highway efficiency, engines tend to last forever, torquey drive
Cons - urea refills, continued complete dependence on oil, expensive high pressure injections systems, emissions worse than gas
Volt
Pros - silent/fun electric drive, very low gas consumption depending on usage, respectable efficiency when on gas
Cons - expensive Voltec parts once out of warranty, compact car, need a plug at home (apartment/city living difficult)
If I was a travelling salesmen, I'd maybe lean towards a diesel. I used to really want one, but got tired of waiting for the ones I liked to come out (Mazda 6 diesel wagon, never came out in US), and then I tried my friend's Volt. Most of us here find electric propulsion rather addictive, it would be hard to go back. Good luck with your choice!
