Will a 2001 Audi A6 4.2L Quattro Parts Car work for a 2003 Audi A6 3.0L Quattro?

What is your question?

Hi, I'm just trying to buy a parts car for my 2003 Audi A6 3.0L Quattro. I found a 2001 Audi A6 4.2L Quattro with motor problems. My car was in a minor front end accident before I bought it so I'm just trying to replace the Front Bumper, Headlight Mounts (Screws, plastic mounting surface, etc), Fog light harness, and a lot of interior parts (plastic pieces for window controls, cup holders, etc). Would this be a good vehicle to buy as a parts car for this instance?
