Jack,
I've never owned a diesel but would consider one. I do want good on road performance, and while the 320CDI has great torque, acceleration is still poorer that the 350. I have been wanting to replace the '98 by early summer--if the CDI was available at launch I would have given it serious consideration. The fact the the 350 is the new 4-valve engine that produces more power, yet has improved mileage, is a selling point for me.
