then what would be the most common oil leak, what should i look for so i know where its comin from, cuz i cant see any, but the mechanic says it leaks oil...

its got 150k miles, i would like to buy a 5k car, but i just dont have that kind of money, i got 3k to deal with here...so i think i can buy this one and get it to really good condition for 3k...

In good condition its worth about 3k...she was selling it for 2900, i found all these problems when i had it checked out, and she came down to 1500, i serously doubt she will come down any farther...
