Tranny Question
But this was the verdict of some of the most respected auto journalists in Europe when reviewing the entire w203 range.
NCAP: 5
Best Models: C240 Elegance, C270 CDI Elegance
Worst Models: C320
Replacement: 2007

BTW - that delay is built into the ECU map for American cars to semi neuter the throttle. The Sprintbooster does not get rid of it - The only way to get rid of it is an ECU remap by a competent tuning house.
Oh and about that delay, thanks for clearing that up. Its the ECU, i always thought it was part of the ESP or something that was restrainning me.
The M271 scares me a little, but I wonder if all of it is justified provided I maintain it properly. Scottisha on here has an 05 C230K with 180,000 on it and no major engine issues ever. I have pigtails fitted to prevent the oil in the wiring harness issue, and it runs on name brand premium fuel and a regular shot of Techron concentrate. I see the V6s having their issues as well. That said, if I could have found a 2005 C320 Sport or had I been willing to pay what the 06-07s were fetching at that time I would have bought it. I was just unwilling to buy a pre-facelift and/or non-sport car because I like the updates and the appearance of the sport.
As for the 135i.. I'm not the type that keeps cars too long. We had a 08 Infiniti G37 bought in Sept. of 2007 that was traded for the 135i with just 24k miles. So long-term reliability is meaningless to me as the 4/50 warranty and free maintenance keeps me from paying out of pocket in what will likely be the entire time I have it. The Benz will be the exception. I will have had it a year on July 19th and I love it just as much as ever. Usually I'm bored by now. I don't see myself getting rid of the Benz for at least three more years.. That's about 90,000 more miles. So about 140,000. *fingers crossed*

I had a choice between chosing a 05 c230 or a 01-03 c320. The c230 looks awesome, engine has a supercharger, great handling lil thing, and was fuel effecient, but I ended up getting the c320 primarily because of its engine and the fact that it wasnt a base model Benz therefore I got the extra luxuries the c230 would never have (FULL leather interior, power everything, Bose, ect.) Your MB is a nice car, sounds like your doing everything there is to keep it running for another 140k mi.
I wonder is it OK to add the Techron concentrate (on my car)???
In my owners manual, it says not to add any fuel additives or something like that.

I know what you mean about a lot of C230 cars being base. I got the power package that added power/memory seat and a few other options with mine.
dont get me wrong, i always use premium fuel (not brand name though) and always thought of adding fuel system cleaners but after reading my manual (it says dont add any fuel additives) I didnt bother with it.

I live sort of between these two towns, so I need to check and see if a Chevron station exists in the other one.
i have 88k mi on my car and it has never been treated with any fuel detergents! (stupid manual said otherwise!)

Now i gotta wait until my tank empties so i can refill with that "holy water"!




Here is another nice valve from a car run without Techron - Excuse the resolution - or lack thereof

so for the past few days i've been trying to find where to buy the Techron concentrate. I went to Chevron, the autozone and even target; I cant find anything. Going to places just to find something small like this is driving me crazy!! Obviously there are cites i can buy it from off the internet, but i dont wanna wait for shipping! Where can i find this concentrate???
lilbenz where did you get it?

just a lil update, i put in a shot of techron concentrate and added premium chevron gas last night.. and WOW, there was a significant amount of difference while driving. This is my own first personal experience i felt right away; engine throttle response is way better, feels a bit faster, and when listening to the engine while idling, its a lot quieter, its overall a LOT smoother.
I highly recommend this to anyone!!!
It was a cold night out, so maybe thats why my car felt faster (cold air=more air ppm=more combustion).
