I have a 2005 nissan sentra 1.8 . this car is fun to drive and gets good mileage. The problems with this car are crazy for its age and mileage. Two worm gears replaced in the tranny, new head gasket, radio can't get stations in, front windows hardly work when wet, fuel filter is in fuel pump, clear coat in really bad shape, already has rusted and repaired spots, and I really am afraid for my kids and thier future car choices...planned break down vehicles?
The handling of this car is good. The stock speakers are good. The engine oil being only 3 qts w/filter is awesome. The gearing of the car for a 1.8 is great. Trunk space and fold down seats are great. Suspension is good till you have over 100lb in the rear.
okay so improvments?. geez, I guess go back to the 1.6 motor, and the tranny that went with it. Stop putting plastic clips to hold stuff and go back to screws. Make a fuel filter that can be changed regularly. use better paint and clear coat. actually just go back to making cars with parts that last, and can be replaced.
