Diesels are not yet popular in Oz as the fuel is more expensive than petrol or LPG. I can only think of two makes that have diesel powered variants....Peugeot 406 and MB 220CDI. I have recently tried the CDI and was extremely surprised at the pickup of that car. It was just a little noiser that a petrol version and you have used to the clatter at idle. Other than that I thought it was great. Beats driving around in a 4 cylinder petrol like mine!
If diesel was cheaper and I do more than my 10km trip each day (yes, I should be walking), maybe diesel would make sense. Then again, I should be driving an E500 as fuel is the least of my worries. If only we have the E500 in Oz.......sigh!!
