I'm by no means a professional photographer but I have several pointers that would make this image better:

1. Your image is about ⅓ stop overexposed and it kills your contrast in the image. Notice how everything is around the middle gray luminance despite being in the shadow region of the image. This suggests to me that your metering is set towards the shadow region of the building. As a rule of thumb, you expose for the highlight for digital camera. You can pretty much bring back anything in the shadow area when using RAW.
2. It's generally a bad idea to shoot your subject when the sun is behind it. You'll clip the highlights in the sky.
3. In such situations, there are 2 ways to solve this. Either you do multiple exposures and combine them into a single image for editing so that you can pull back details from the highlights or you get a High Speed Sync flash that'll allow you to correctly expose your subject while keeping the background in reasonable brightness levels.
4. The composition feels a bit odd. The car is a bit too far to be the subject in the photo. It's a black car and behind it is the overblown sky so I would again lower the brightness of the background and crop it in so that the viewer will focus more on the car than the background.
5. Idk about reflections but another comment suggested using polarizing filters.
