Frankly, I *wish* that GM would release the police Caprice with a diesel engine (rather than a gas-guzzling piggie V-8) when it comes out for civilian use in 2014. I’d love a 30+ mpg “land barge” — I drove a Caprice wagon in college before some fool stole it and exported it to Saudi Arabia(*), and it had awesome carrying capacity, got high-mid 20s highway MPG, and handled better than any SUV.
