My son has an '02 Golf. We bought it for short money, and it's been incredibly good to him. We've replaced suspension, timing belt, rear calipers, brake rotors and pads, and, of course, filters and fluids. We put new injector nozzles in it last year.
It has 362K miles on it. The steering rack seems to be consuming a bit of PS fluid: we've added about 4 oz in the past 6 months. When he was here changing the oil I asked him if he felt it was worthwhile replacing the steering rack if needed. He said, "of course! Where else am I going to get a car this good for such a small amount of money?" I think there's your answer. Next month it'll get a timing belt service, perhaps a steering rack.
My daily is an '02 Jetta Wagon (not a Sportwagen, btw), with 366K on it. I never hesitate to have whatever it needs done to it. That way I continue to enjoy driving it. I bought it new, I don't think it owes me anything. But it's a great car, my favorite, and in my opinion, there's nothing like it.
Get it fixed and drive on!
