It is done with adjusting your shutter speed. Do a search on google about it, and you will find more info than you will ever want to know.
To make a the background, foreground, or the object blurry, you need to adjust Aperature, not shutter speed. Shutter speed should be set to whatever the film recommends. As to which aperature setting you want, I can't tell you. I took Photo in HS, but that was a while ago.

Just had an epiphany!
The smaller the aperature setting, the more things will be in focus. The bigger the setting, the less thing will be in focus. You will need to play with it though. It depends on how much background you want in/out. Plan on taking at least 5 different shots of the same shot to get it right (change the setting for each shot).
Once you take 200 shots or so, you will get used to what you like.
Also, you want to try to keep the top-right corner of the picture dark. When someone looks at a picture, they usually start at the bottom left, and move up to the top-right. If the top-right corner is really light, they won't want to look at the picture anymore. Any sort of dark color will work.
You will notice this when you look at professional pictures.
The top-right corners of these pictures weren't anywhere near as black as they look here. When they converted from 35mm film to a print, they project extra light just on the corner to make everything appear darker.
Here is some info I found. A good place to start.
Another thing I will say is the car will not change. It is what it is. You can change the angles all you want, but you will always be looking at the same car.
The background, however, can change very easily. That is what you want to concentrate on. Here are some quick photos I took of my car.
That is a cropped version of the original. It removed most of the road, and moved the left/right edges in more. The top-right corner is still too light, even with the shadow on the garage door.
Here I didn't include the entire car. It's ok to do that, but since 95% of the car is there, it leaves you to think "where the heck is the rest of it?" (i.e. If you want to take a picture of only the wheel & the space between the fender after a suspension drop, it serves it's purpose to just zoom on the wheel/fender. Back to my pic; Some cropping will fix the right & top sides of the picture can be fixed. But it's a complete waste of a picture w/o the entire car.
