This car is supposed to get up to 32 mpg and the most I have ever gotten is 25 mpg
That does not mean that it will . That is probably the highway miles per gallon. Since you did not disclose your normal driving pattern ( all city - 1/2 city and 1/2 highway ) it will be hard to say if your MPG is correct.
12 years ago when it was new, it probably did.
Key words “Up To”. On rare occasions a car will get better than the estimate.
But 13 years old, highly doubtful you could ever achieve that.
Looking for the EPA estimates , even the Hybrid is rated for 29 highway, 26 overall. And most people don’t drive like the EPA cycle.
Where did you come up with the 32 mpg figure?
