In the first shot, your shutter speed was only 1/100th of a second, which is generally fast enough with a wide angle to reduce motion blur (camera shake), but a faster shutter speed is better. Second pic your shutter speed was 1/1600, which is plenty fast. Faster is sharper. In the first shot, your F stop was 29! That's overkill. A higher number (smaller aperture) does increase the depth of field for focusing, but many argue that going past f8 or f11 will reduce sharpness even though the depth of field increases. Something to do with the light bouncing crazy off the sides of a small aperture having a greater effect. In the second shot, your f stop was 5.6, which you can see did not give you a big enough depth of field to keep the entire car in focus. There is also a sharpness setting in your menu. It's usually set to a balance to make people look good, but if you are shooting cars and things you can increase the sharpness in camera. Go to menu > shooting > picture control. BTW, nice car!
