 I bought the car used.  The battery light came on intermittently.  The dome lights and signals would go on for no reason in the middle of the night.  I went through 3 batteries in less than 5 years.  The electrical issues became worse as time progressed.  It was determined that the "cluster" was bad.  There was an unidentifiable drain on the battery that got to the point that a brand new battery was burnt out in a matter of months.  When a new battery was installed, the car was dead the next morning.   Getting rid of the ghost in the electrical system would be a costly repair -- more than the car is worth.  My mechanic found that these cars are notorious for electrical/cluster problems.
