Nissan Altima - 2003 Review

I purchased a brand new Altima in 2003 and didn't have many problems at all.  Until February of 2009 when the car was 6 years old and had only 64,000 miles on it.   I took it in to be serviced because the service engine light came on and the the dealership informed me that the engine was shot (blown head gasket, oil in radiator etc.)  I had absoutely no warning because it ran fine.  I took very good care of the car and had service done regularly.  I am very upset by this experience and will never buy another Nissan.
