2006 Honda Civic Engine Mount

Hi, I'm going to buy a honda civic 2006, the buyer told me there is a problem in the engine mount from about 4 months & it needs to be replace !!
My question is:
Do you think that problem made another major issue to the car, as it has the problem since 4 months, or just replacing it will solve the problem, and everything will back normal .. ? Do you think its ok to buy the car & just replace the engine mount ?


Thank you very much.
