I drive a 2003 Ford Focus that has about 145,000 miles on it. I still have the original struts and muffler on it. Am I pushing my luck with that? My local repair guys believe if it ain’t broke - don’t fix it! I love them. I get my car inspected every year and rarely need anything done to it. I also don’t drive over 5,000 miles a year now that I’ve almost retired.
