Can they service alfa romeo?

I don't know but my experience with them was terrible. Price was ridiculously high and almost impossible to get them on the phone once you leave the premises. Never go back .

YESSSSSS VERY KNOWLEDGEABLE , TELL YOU EXACTLY WHATS THE PROBLEM AND GIVES YOU A GOOD PRICE..... DO IT

That depends: did you purchase from them? If not, then they are not obligated to do so.
