Pentax K1000 Manual Focus SLR Film Camera with Pentax 50mm Lens (Renewed)

I purchased this Pentax K100 for nearly $300 in what was titled “Refurbished - Excellent” so in my mind I was practically buying a new if not nearly new camera. Although for the most part the camera seems to work (I haven’t gotten a chance to see how the photos come out), it is definitely not in “Excellent” condition.- The 50mm lens it comes with has a slight bend on the edge. Nothing that may impact the quality of the photos but still not “Excellent” condition- There’s a dent in the bottom of the camera itself. It’s pretty noticeable and a bit concerning since it may be the reason to some underlying issues- The viewfinder has specks of dust in it. I’m not taking about dust in the mirror that I can wipe off with a cloth but dust IN the viewfinder. Definitely distracting when taking a picture- Lastly, it seems like the light meter does not work. I put in a brand new battery so I know it’s not a battery issue. When I go outside and have my camera set to the proper “Sunny 16” method, the light meter displays that the photo is currently under exposed. I used a light meter app on my phone to help my find the correct lighting and when I set my camera to those recommended settings, the light meter on the Pentax still says I’m underexposed. It makes the whole process confusing because I don’t want to risk takand under / over exposed photo.With that being said, I will get my first roll developed and most likely return the camera. If I am paying $300 for this camera and it is advertised as “Refurbished Excellent”, I expect 0 flaws. I wouldn’t mind purchasing the camera again as it wasn’t in completely terrible condition. I’m just afraid of buying a camera in “Excellent” condition and it’s even worse than the one I currently have
