ahah hell yeah take the car. but befor you do have it checked out by a mechanic.if its not worth it try n get the money.if you going to look youself, look at miles, make sure antifreeze and oil is good, that theres no iol or leaks under the car and ask the guy if you can see where the car has been parked for the longest time because if it has leaked the ground will show it, make sure all the lights(such as check engine, exc) lights up befor you actually start the car.(people jsut disconnect the bulb to make it look like the light isnt on but the car could really have a problem) and you know just look aorund. test drive it. nd aparently its his fault so try and squeezr $500 out if him for taking up your time.
