Not that big of a deal any more with modern engines/exhausts. I wouldn't suggest running the car for extended periods in an enclosed space but a few seconds/minutes in a garage won't hurt you (assuming the engine is in decent tune and pollution devices are working). Yes, the cats aren't working at first, so you will get a small amount of CO, but they warm up pretty quickly.
