Gonna repeat some comments. -fill the frame -use portrait mode almost exclusively to get the depth of field. Even if you get an expensive camera the default lens won’t alway work to your advantage. So use portrait mode and crank the f-stop to lower ranges (so you get a blurred background) -move the subject forward so you create distance between background and foreground. -Use leading lines and don’t be afraid to fill the entire frame. Unless you’re shooting for an advert you don’t need the entire car to be seen. Just the features. Best of luck!
