The odometer doesn't work about half the time and the speedometer doesn't work when the odometer quits.
Five of the six '97 LeSabre's I looked at when shopping had questionable odometer readings, meaning the odometers on those also weren't working, or had quit working at some point.
Got to wonder what was going through this guy's mind: "...duhhh, the only thing I know is that the odometer don't work? Oh, wtf, I'm gonna post a review anyway even though I got nothin worthwhile to say"
