I bought a 2014 Chevy Spark with 3,500 earlier this year to commute to school (50-80 miles weekly) I used to take the freeway but i toned that down and started taking city streets. Currently it has 5,400 ish, and it has been a good reliable car until now. Recently I have noticed the engine becoming louder from inside the car (I'm aware you can hear the engine in these cars) but i remember it being more on the silent side, it now sounds like a truck.
It still drives smooth and all but the sound is more hearable when i fully stop or have it on park. I don't have the AC on but when i do turn it
