Nice car but too noisy

I took a test drive recently.
Found the car nice overall except the too much noisy engine and AC.
It was feeling like an Indica Diesel.
Dealer told, the demo car recently had a major accident and that was the reason. Not sure hou much to trust his words.
Can some one who already owns this car or had  test drive share his experience in this regards?
That will help finilazing my first car :)
Good fuel economy, Good style, Nice interiors, good pickupToo noisy engine and AC
