Speaking of which, have you seen any of the new propane buses? I looked them....
They take the Ford 6.8L V10 which was so so to begin with, convert it to propane, then take the light duty 2500 series transmission for the V10 and throw it into a 30,000lb school bus! When I was in high school I asked one of the mechanics and he told me all about them... The mechanics are not allowed to service the buses because they are propane, not diesel, so they have to go to the dealer for almost everything, second the transmissions are already showing signs of great stress, my school only had them for one year at the time, third the motors will not last long, here in up state NY we have hills, some big hills, and the motors rev about 4,500~5,000 rpm to climb those hills... That will sure make the motor and transmission last long...
Also, I must say, that I am sad to see the crown vic going away. They were so cheap to fix, I can already imagine the police departments needing bigger budgets for the Tahoes they keep buying and uni-body cars that die easy...
Its a great example of a good ol' American car: Big 4 door car on a real frame, V8 under the hood, a transmission with less than 4 speeds (we don't need more than that lol), rear wheel drive, and a floater... just missing a Big Block and a 5,000lb+ curb weight haha...
