I have an 87 300e. Yesterday I test drove a 90 300e for my daughter. I was amazed at how sluggish the car was during take off and up a hill. Not only was it slow but scary. The car would get going but the shifts were very rough (almost a jump into the next gear) at higher than normal RPM.
My daughter noted a vibration on the passenger side wall when the car was struggling up the hill.

I read a lot of posts thatcovered everything from temp sensors, tune ups, modulator and tranny replacements. I'm reasonably handy with a wrench but won't venture inside the transmission. The car was nice other than the sluggish take off and gear change issue. NORMALLY I say run away, but my 300E doesn't act anything like this one.

Timely posts with suggested causes might sway me to make an offer.
Thanks for the interest.
Regards,
Bob

Maybe it had a really bad vacuum leak?
