A true workhorse

I bought my Lumina Euro 4dr in 1995. It had 30,000 mi. on it. It now has 185,000 and is still running strong. It has its original timing chain (or belt??) original rings, valves, fuel pump, transmission, water pump, etc. In fact, I have never had a single engine repair; the car just keeps on humming along. What makes this even more amazing is that my maintenance habits are horrible. I change the oil every 10,000 miles or so, and don't do much else. I know that this is not case with most other 1991 Luminas, but I have been blessed with something that came off the assembly line as near perfect as possible.
