Hello I am new to this forum so first of all hi to all .

I am looking for an ML 350 for my dad but know almost nothing on them.

What's the difference between sport and premium plus ? (yom 2014 ).

What to look at when buying these cars ?

Is there alot of difference in power between 250 and 350 ? (I know around 50 bhp) but anyone tested them both and know how they feel in real life ?

Thanks in advance

Josef
