I took the new jeep liberty CRD for a spin. It really was a fun to drive. it took only a few seconds for the glow plugs to warm up and it was ready to go. The engine is almost quieter than my 4.0 litre.
It has good pep from the get go, due to all the low end torque and the five speed automatic was smooth.
The 2,000 dollar adder does not make it economical. It would get nearly 50% better fuel mileage. But it would take like 5 or more years to earn back the initial cost, and the fact that diesel is anywhere from 25-35 cents more than gas. I may wait until the hype has died down.
