Anna, Don't let your husband get away with the "I told you so's" Until you have had a chance to check into the advice you have gotten on this board. I'm being sincere in this. I have a 300TD-T ( that's a station wagon) It too is slow when my wife drives it, when my 15 y.o. daughter or I drive it this is NOT the case) I also have a 300D NON-Turbo that I drive daily. Think about this, 140 miles of start/stop driving every day. ( rural press route) Mostly on dirt roads, but I do have quite a bit of In-town (approx. 14 miles) I have to get on and off of a couple of major highways too. Although I am a hardcore dieselhead. (6 diesels in the driveway) I still know what I "can" expect out of them. I wouldn't try to run a drag race with my dually pickup, but it's NOT slow either. The other turbo diesel I have other than the wagon is a VW Jetta. I don't know of many gas cars that accelerate much faster than this car. 3rd gear 60mph just as fast as you can shift burning rubber and blowin'smoke! The 300D wont burn the tires, but it will definately get out of it's own way. Especially since I cleaned out around that kickdown solenoid under the floor mat! If I pull out of the driveway nice and easy and then floor it, I can take a ballcap off my head and put it in the back seat with both hands on the wheel. Unfortunaltely there is a stop sign two blocks from my house! I can still hit 40mph. and have plenty of time to stop. Just getting a MB tech. to look at your car (well meaning as he might be) does not render his decision "correct". You need someone who is familiar with diesels. I bought a VW diesel from a VW mechanic last summer who couldn't get the car to run, period. This despite installing a brand new crate engine with a new head, new inj. pump, new injectors etc. He had been a VW mech. for 40 years and couldn't make the thing go. I paid him $500 and towed it home. Half an hour later I was driving it down the road. My friend bought it from me and is still driving it daily. ( when his wife takes the MB away from him) My point is this not all MB, VW , or any techs for that matter know all there is to know about all models. They may well be familiar with all models, but they specialize in a certain area. Unless your tech is a diesel specialist....... 'nuff beatin' the dead horse. Just trust us, it can be fixed and you will love the car! More times than not it's something simple!
