I had a basic cross trainer too. It did a good job for training arms and legs but also got the heart rate up higher than running so good for cv training. It could be a bit creaky and noisy but that might not be an issue in the garage. Make sure it you can change the resistance and read the reviews.
Cheaper alternative is get a turbo trainer, if you have a bike.
