Did I waste my money time doing a timming especially by the dealer. My 2000honda accord se had 23,000 miles 8 years and garaged. I was told that your timming belt should be replaced if you had 100,000 miles or 7 years which ever comes first. So I had my timming belt, water pump, belts, ect. So does this car have a interference engine

I am skeptical because I never replaced timming belt, water pump at so low a millage. Does the time factor really dry out the belts if your car is garaged.
