Ok here is where i'm at. Pardon the lack of thenical terms to describe my issues, i don't really know much about cars.

I bought an audi a4 2002 130,000 miles from auction for 3,500 (including tax and fees) and spent another 1,000 tune up and replacing the cat converter to pass smog test. Then i went to a private audi mechanic and they gave me a list of problems my car have and if i want the car in a decent shape i'm gonna need to shell out another $3,000. Here is a pic of my estimate.

Apparently the car was over heating and to fix the problem they botched up the electrical work for the coolant fan ($400).

Coolant flange leak (325)

Cam tentioner leaks ($400)

He also said my tires and shocks are shot and need to be replaced. ($1300 for shocks and 500 for tires.

Tie rods blown ($350)

drive belt ($100)

The car was in limp mode when i brought it to him but he found one of the pins was bent in the computer magual, now the boost works normally and drivse like a normal car.

But when idling at a stop sign the rpm seems to drop drastically, i read somewhere that it might be a sign of transmission failing (knock on wood) or intake leak. Video of car accelerating and idling. Audi a4 rpm - YouTube

So now i'm at a cross road, i really like the car (interior and exterior) and want to keep it. I was thinking about fixing the main components (leaks and electrical) and fix the other stuff later. i'm broke now lol i'm still a college student. but the mechanics recommended if i can find a good deal to sell it, how much would it go for on craiglist?. Can you guys give me advice. ANY ADVICE or encouragements lol.

 

If you had the time and know how I would say keep it. Get out while you can!
