Help choosing a university and language school

Hi there!!

I would move to stuttgart or somewhere in Germany soon enough.

(Not sure yet which city it might be.. coz I am looking for some university which can teach me about car engineering major
and now just collecting some info about this and will do during my German studying in Language school as well.^^)

I just learn some German in my country ...one year?;; and need to get a certificate of qualification for DSH to attend a university.
Already studied with this major which is car-engineering for two years in my country but wanna learn deeply about this.
That is why I chose study abroad.. however it is super difficult to get right info and decision as well...

I guess it is necessity to take some language school before go to university.
So here is my point..

Which language school is good for me who will attend to university?
I still have no idea what is your standard to choose this and how do you guy do this??
and which university is famouse or good to learn car-engineering more deeply in stuttgart?
(or if you wanna recommend to me any other place but stuttgart you could do that and also great for me as well^^)

Thank you for time and I am appreciated your all concern.!!^^

Some universities offer prep courses for the DSH, usually called Studienkolleg. Try googling that and you will find the Studienkolleg pages for various universities.
