Im just wondering how many miles can I expect out of my 2003 P5... Im currently at 150k miles but there is a boat load of rust. Not sure if I should sell it when I can afford another car or if its going to be a money pit. what is a reasonable ceiling for miles I can expect to get? I heard that the pistons oil holes get plugged and Im worried because the previous owner def didnt do me any favors with oil changes
