If you're not going to replace parts as they fail then buy a new car. Replacing parts as they fail is part of owning a 20+ year old vehicle.
Very funny. Apparently either you haven't read the rest of the posts, or you're a new car salesman just pushing for business!
What smart people do is maintain their vehicles so that we're not driving around in a car filled with parts that are just ABOUT to fail; I know people like that, and their justification is, if it ain't broke, don't fix it. These are the folks you always see stuck on the side of the road in the summer with blown radiator hoses, helplessly staring out into traffic waiting for someone to rescue them, or repeatedly calling AAA in the winter with dead batteries, screeching brakes or fan belts, and oh yeah, windshield wipers that can no longer clear a path on the windshield: Those who wait to replace parts when they fail. I don't know; maybe they like being stuck on the side of the road. Are you one of them? I don't want to be. That's why as soon as I saw this problem with my suspension, I want to fix it asap, and I'm not going to use this car for anything other than getting it to a shop until it's taken care of.
I just purchased this car recently and within a year or so, will have gone through it and replaced anything that is reaching end of life SUCH AS ALMOST 20 YEAR OLD RUBBER AIR BAGS. Do you wait until the rubber falls off of your windshield wipers in a rainstorm before you go to the store to get new ones? Sounds like it to me!
What's really funny is that I have a local mechanic who said something similar. I had an a/c compressor that seized up in the middle of the winter; I took the truck to him and asked him to replace it. He told me it was so old (it was 9 years old at that time with about 120K miles on it, which is nothing for a domestic 1/2 ton pick up that doesn't get used for hauling very often), I should not put any money into it and should buy a new car. Where upon I told him that if he didn't want to repair cars, why was he working as a mechanic, that he should close up shop and become a car salesman. That pissed him off, but it didn't matter, I was leaving anyway. The rest of the truck ran fine, the body was rust free and in good condition. A new one would have cost $35,000 plus, vs <$1000 to repair the old one. I kept that truck another six years with I think, only changing the brakes and one alternator, both BEFORE they died, but as soon as symptoms that they might started showing up. Now unless you have a ego that needs to show off how much money you can waste, why would you buy a brand new one when the one you already have only needs minor repairs?
Some people are just hard to figure out.
