car guy 
2002 Nissan Altima Sedan 2.5 S 4dr Sedan (2.5L 4cyl 5M)
good car BUT...........
 Bought this car with 109,000 miles on it. reallygood deal, the car was awesome, but after 3 months the check engine came on so we took it to the dealership they said it needed new spark plugs $120. After it got fixed we drove about 300 more miles and the check endine light came on again. so we took it to the dealer again. after a few days the dealer said that the car had a blown head gasket in the engine and the coolant was getting inside the engine, the estimate for repairing was $2000 and that is a lot of money. i think that he was lying because it doesn't cost more than $900 to fix it. I think i am going to sell this car and buy another 2002 altima with lower miles.
