I have a 98 Dodge Intrepid ready to be repossessed. I bought the car in 2001 with 53000 miles on it. 2 years later the engine blew  with no warning as I was getting off I-95. It cost me $4.200 to replace the engine. A year later the 2nd engine blew and again with no warning as I was driving on I 95. I replaced the engine again at $2400 because I still owed money on my loan. The second engine lasted about another year and now overheats after driving it for a half hour. I took it to the mechanic and he said that the heads are bad and the engine is cracked. I will not put a 3rd engine in this car. I still owe $5000 on my loan and cant afford to pay for it any more since I went and bought a 2001 Honda that I need to get to and from work.
