I'm in the market for a 08 Nissan Altima 2.5s. I currently have a 95 Honda Accord 2.7 V6 with 150k miles recently broke down. The mechanic "says" the camshaft and crankshaft sensors went bad and the job would cost about $750 to fix. Besides this issue, the car had a strong engine (great acceleration) and was in fair to good condition aside from having only one working power window (electrical problem), broken odometer, broken fuel gauge and small oil leaks which one could consider cosmetic. KBB value for Private Party is $2,985 in fair condition and $1,515 Trade-In value. My question, should I spend the money to fix the car and use it as a trade in for the Altima or scrap the car and cut my losses. I'm worried that a private seller wouldn't buy the car because of those forementioned issues.
