Typical problems known to early Saturn's are the problems I've had with my car.
The upper motor mount has failed twice. I replaced it the second time with an OEM unit from the Saturn dealer, which has been redesigned, and seems to be holding up a LOT better than Autozone's offering.
Alternator failed shortly after I purchased the vehicle, 100$ later I'm back on the road and it's been happy ever since.
Interior is fastened together with cheap plastic clips. These break frequently causing different trim peices to rattle. Luckily Saturn sells a 1.50$ reattachment clip. Takes some work, but does the job and stops the rattle.
Window regulator on the drivers side is missing teeth on one of the gears. When I roll the window up, it stops about 1/2" from the top.
I cannot describe how economical this car is. I can't remember the time I got less than 30mpg, and I can go 360 miles on one tank of gas. Maintenance is beyond cheap, with the engine's DIS (distributor-less ignition system), and Multi-Point fuel injection.
The car is suprisingly quick, these will go 0-60 in 8.7 seconds, and handles quite nicely as well. Engine is responsive, has a lot of low-end torque, but has a lot of upper-end power toward redline for those sprited driving occasions.
Interior isn't the greatest design as it's all made with hard plastic, and isn't the quietest over bumps, but has held up well and looks nice.
The ride could be softer, but considering this car is 11 years old-- maybe I'm looking at new struts in the near future.
