I didn't seethis thread when you posted it.
"Glare" is normally reflected-blue light. It causes pain, like HID headlights and the fake HID (blue) headlights.
In your pics, you could reduce the reflected light with a properly adjusted polarized filter (adjusted = rotated). That would help with the window, and paint reflections.
The second issue is the over exposure of the image. The light meter in the camera is calibrated to capture images at mid-tone (half way from black to white). Your Jeep is darker than mid-tone. If you are shooting on "AUTO", the camera is adjustin the setting so that your dark Jeep will turn out mid-tone. Because of this, everything is over exposed, including the Jeep.
You shot the Jeep on a perfect, cloudy day. Soft shadows and good contrast (not to much contrast). Try it again on another cloudy day, and under expose it by 1 stop.
In the mean time, edit the image, and bring down the exposure (brightness), and see if that helps.
Here is an example, with your 2nd Jeep image.
I removed a little Blue, and decreased the exposure, until the grass, trees & bricks looked good (still might be a bit bright). The tires also look more grey / brown / black, instead of blue / grey / black.
Here is the original
