Luckily, nothing major so far.
A couple of really annoying squeaks have developed. One from inside the dashboard and the other seems to be coming from the right-rear passenger area, where the door would be if this was a 4-door car. They are both a chirping type of noise and very annoying!
I find that the transmission is difficult to shift into first and reverse gears at times.
The ignition gets stuck sometimes. This is a very common problem with these Saturns.
Overall, I really like my Saturn. I think it's a very stylish and distinctive little economy car.
The interior is by no means plush, but it is reasonably comfortable and roomy for a small car. The interior is nicely styled for an inexpensive car, but the plastics are just too cheap looking for my taste.
The overall performance of the car is pleasing. The steering is tight, firm, and responsive. The suspension gives a comfortable and controlled ride, but there is too much wobble during quick manuevers. The brakes work very well on this car and the brake pedal is firm without being spongy like so many GM cars. Overall acceleration with the standard engine in my Saturn is adequate. It feels quite zippy driving around town, but feels weak when trying to accelerate onto the highway quickly. Once you're up to speed, the car has no problem maintaining speed and passing.
There have been a lot of complaints about Saturns having too much interior noise. Accelerating and cruising doesn't seem to produce any louder than normal noises in the cabin for a small car like this. I find the Escorts I've driven to be a lot noisier inside than my Saturn. It's not too noisy for everyday driving.
My only concern with this Saturn is reliability. From all that I've read up on, the SL and SC Saturns have all kinds of reliability issues. Both manual and automatic transmissions are failure prone. The standard 100hp engine has head gasket problems and the 124hp engine has oil burning problems. Saturn quality seems poor, but what attracted me to my SC1 was the good looks, decent performance, great fuel economy, and low price. Whether it'll last or not is hard to tell at this point. I don't know if I'll buy another Saturn in the future or not.
