I have a 2002 Cavalier Base Sedan it has the 2.2 liter ohv engine. I love the low end torque rather have ohv than the dohc. I got it June of 07 it is my first car it had 52k when I bought it now has 110k today is march 25 of 2010. I average 34 mpg. Only thing was is this past Christmas the fuel pump died other than that it is perfect. I have modified it a bit I installed a flowmaster delta 40 muffler and converted the stock intake into a cold air intake which has helped economy and performance plus the muffler gives the car a good sound. I will own it till it dies which looks like a long time.
Performance, Reliability, Looks, OHV engine love the torque mine is putting out 155 lbs (est) after mods and it is a big help when your at the light against a focus and I have beat a lot of them thanks to the OHV.
Wish they would have added another 40hp and maybe 30 lbs of torque. Other than that maybe a different speedo instead of the conventional 110 maybe 140 to look a little sportier.
