Measure the space in your car both for height and length. Then you will know what will fit. I use a crate made to airline specifications for my car. For size comparison to your car I have a PT cruiser with the back seats folded up. The crate fits perfectly and I use tie downs to make sure it doesn't slide around. Inside the house I use a less strong crate from Petmate. At shows I use a folding crate. Never leave your dog alone in a folding soft crate though if you want the crate to last. They can bust out pretty easily from those.
