'98 318ti owner looking for suggestions

[coonbear]

Hello, everyone. I have a '98 318ti for about two years now and I need your suggestions on what to look out for in terms of possible parts that will need replacement within the coming year and such. The car currently has about 68,000 miles on it. I have to admit -- I don't know much about cars, but I do take good care of my ti such as prompt oil changes and services. I already got the belts, water pump and battery changed about two weeks ago. Now I have more serious problems and they are busted ABS sensors, airbag sensors and seat sensors. The dealership has already given me a quote and I just need to know how much more parts replacement should I be expecting. I love the car, but I am also going back to school. I will really appreciate anyone of you giving me genuine advice and suggestions. Thanks much in advance. =)
