IMO,no they are not dependable.
Your car is 18 years old. What is your expectation? The 90's and 2000 models continued to degrade in quality as the brand moved toward extinction. I have a 91 Trans Am that I have owned since new and take extremely good care of. It has 160,000 miles on it and has never been a problem. The condition of the car is most important and if you do not know its history, I would look to replace it fairly soon.
