I vote she get which ever car she can afford.....
Just kidding, I am sure i'll be first in line to buy my kid a car when the time comes. Our first is on schedule for a june arrival. I am thinking S55AMG
I have often thought that a standard is a good first car. I think it's important to know how to drive a stick, you never know when it will come in handy and I think it keeps the driver alert and involved.
I am not sure if I would get a Mercedes as a first car for my kid. With all the systems and potential problems I am not sure it would be worth the effort unless you are handy and a DIY. Kids seem to find a way to break stuff.
I don't want to make any enemies on this site, as without your help my 300e would still be sitting in my garage. Plus I enjoy the threads and personalities. But I find the jap cars bullet proof, easy to work on, easy to drive and if new enough very safe.
Maybe my 300e wasn't properly maintained prior to my purchase, even though I have the records from previous owner and he did all factory recommended work at dealer.
Just my 2 cents,
