The sunfire and the z24 cavalier of course are the same car.
The 2.4 is an excelolent engine and of course parts are dirt cheap
Not sure why some bash these cars, either they hear stuff or have had a bad experience that was odd
I have had 3 of these cars over the years and all were excellent
My 1 had 245,000 when I gave it to someone to help them out. 4 years later I still see it from time to time
My second one I bought with 16,000 miles. at 270,000 the bumper fell off the body. I bet a person we could put a battery in the car and start it. I won 50 bucks even after it sat for over a year.
My third one was sold to a buddy it needed a k member. 75 bucks 4 hours and with 250,000 the car runs like a top
I have gotten over 750,000 miles out of these cars with total investments including purchase of less than 20,000 dollars over 12 years.
I call that a bargain
I say if the car is not rotted runs good and has had good service records it is good for another 50k plus
Parts are dirt cheap.
Major issues were brakes watre pump and the ignition distriution block
The water pump is a pain in the arse but everything else was easy as pie
I will buy another one just as a gas saver.
hope this helps
