Expect numerous generator failures. To reduce the number of repeat failures when they occur, replace the battery at the same time unless it is less than about two years old.
Finding replacement parts is no different than for any other popular car brand. You won't find vehicle-specific parts new like door trim panels and upholstery but the aftermarket suppliers do a real good job with everything else. My biggest concern is with all the unnecessary, unreliable, complicated computers. You will need to buy replacements through the dealer and have them programmed to your car. GM designed their cars that way to make money from you. You'll need to hope your dealer is willing to work on older cars and will keep the equipment to service them working. My daily driver is 25 years old. I just replaced the wiper blades for the first time and I'll be replacing the front brake pads tomorrow. The pads had to be ordered and took one day to get. For other types of parts you and I can find them in salvage yards.
