I wouldn't use a fabric crate for an 8 week old pup full stop -they can be chewed very quickly by a determined dog, and even vigorous scratching can easily get them opened and/or damaged. They are really only suitable for dogs that are already used to be being caged and not worried by it, and when you are at shows and stay WITH the dog.
It isn't so much down to what you use for car journeys, but training the pup to liking the journeys. Feed in the car without going anywhere, take very short journeys with a really nice toy or bones to occupy the pup, use the car to go to nice places for walks, don't make the mistake of making the early journeys all about going to the vet. And make it frequent. You can safely go places before pup is even vaccinated. Pop pup in car, drive a short distance, stop and just feed treats, then go home again, several times a week. Many pups are car sick but they do grow out of it, and the more journeys they make, the quicker it tends to happen. Most showdogs that are used to travelling more or less every weekend of the year absolutely LOVE car journeys, they see the car as part of their home and feel safe there.
