Have you ever driven an E300 Turbodiesel?

I don't think you can fairly issue an "I'd never have one of those because I have to pay $200 every 100,000 miles to change the transmissions fluid" rants until you actually driven one and made the decision that the extra $200 over a 5 or 6 year period was not worth the 6-7MPG bonus, gasoline car performance, HVAC systems that actually work and the vast array of other improvements that 20+ years of engineering work will get you.

By the way it might warm your heart that the official position of MB is that the new 722.6 tranny NEVER needs to have the fluid changed - their position is the transmission fluid should be good for the life of the car. Deltafixer is just doing a little extra preventative maintenance here. This is why the 'no-tamper' plug is installed - MB does not think you ever have to change the fluid.

So maybe you should upgrade to a newer turbodiesel - think of the money you would save by never having to change the transmission fluid

BTW I'm getting ready for my 30K filter fuel filter change - do you want the old filters?
