Considering C400 but worried about 7 spd trans?
Read a number of threads regarding problems with the 7 speed, any fixes or advice?
Any other issues to watch for?
These are about $15-16K cheaper than the C43, I am guessing a tune & coilovers would bridge the gap?

Don't buy it unless you can test drive the car for AT LEAST 1 hour, mostly shifting between 1st-2nd-3rd gears and you really like how it shifts.
Otherwise you'd be better off spending more on one with 9G even if you'd have to delay the purchase.

A gaggle of MB's
I have never had any of my customers have "performance" or "driveability" issues with the 7-speed - we did have one C400 that required tranny update - frankly that has been it.
From my side - I always spend time with my performance "oriented" customers before and after sale driving their MB and getting a good handle of their style of driving and what their MB will do ...
Keep the beat !

All of the shifting related issues I've experienced have been on all Mercedes transmissions, the 7G, 7G+, and the 9G that I'm driving now all eventually at times exhibit poor shifting characteristics in 1-2-3 driving around the city. I'm just used to it, and it really just is the way they are.

I have a C450 with the 7 speed trans and had a lot of poor shifting issues in the beginning. After pushing my dealer twice to fix the issue they did a software update and has been shifting perfectly ever since. The deal never acknowledged the issue though.
