Not so happy 
2005 Nissan Sentra SE-R Spec V SE-R Spec V 4dr Sedan (2.5L 4cyl 6M)
Used to love it
 My son test-drove cars for me and decided on the Nissan Sentra. Brought it home and I loved it. Had it for three years and 1 week, made the last payment, and the next day the Service Engine Soon light came on. Drove immediately to the dealership and they said the head gasket was going and needed to be replaced -- on a three year old car. Are they programmed to have problems as soon as they are paid for? Cost me $1,245 yesterday and they recommended on the receipt that I put it an for an additional $600 more in repairs. If you keep up with oil changes, etc., a car should last longer than three years.
