CRD Diesel's

Was thinking the diesel engine out of the 300c's. If cruising and km's were more your target it would be a good option despite the extra price of fuel, in Aus I think standard unleaded which is 91 i think is for example 1.35 on average, diesel about 1.55 per Litre. Giving the diesel engine guys are getting incredible figures for economy I thought I might see if that was a viable option. Only 160kW but with 500+Nm of torque I reckon in an A bodie it would be a quick car, not a new hemi but you can't have everything.Any thoughts??
