Used 2013 Toyota Prius for sale in Asheville, NC

I purchased this Prius last December from the owner For $8000.
I haven't had any problems with it. I recently put new tires on it, had all the fluids changed, and had it inspected last week At the dealership. I also had new brake pads put on and the rotors Balanced.

The reason I am offering it for such an inexpensive price, is because I feel like there something wrong with it. I took it to the Toyota dealership and they couldn't find anything, though they recommended the spark plugs need to be replaced. I feel like it's making a strange sound and having a hard time accelerating on occasion. I'm not in a position where I can get major work fixed on this car if it comes up.

In addition there is a dent on the back bumper, A dent in the front hood ( which is slightly crooked), and a scratch on the side of the car

There is, 140550 Miles on it

I am also willing to make a trade For another vehicle
