Piston Slap: Hacking the Unrollable Odometer?

Brian writes:

I had a conversation with someone the other day who claimed his mechanic rolled back the odometer on his car. This is a late-model car with a digital odometer. I always thought digital odometers were protected from this, but a quick Google search reveals that it’s actually quite common and easy to roll back a digital odometer. I guess this is now something a buyer has to worry about on top of everything else when buying a used car.

For example, how could you ever tell a car was rolled back — say, 10,000 miles — when the car is legitimately in good condition?

What are your thoughts on this? And how can a buyer protect themselves?

  • Arthur Dailey The only TR-8 that I knew was a 'project' car that sat in the same driveway for many, many years. Did however have a friend with a TR-7. Can confirm that the instrument panel, interior materials such as fabric/upholstery, ergonomics and in particular the seats were superior to my Corvette of the same vintage. However in the first week that my friend had his TR-7 while pulling out of a shopping centre, his driver's side door 'fell off' the car. Quality control was to put it mildly, primarily just a 'rumour' at B.L. during that period.
  • Kcflyer Son has about 3000 miles on his ND now. I've only driven it a handful of times. Great car. I'm biased but I don't think it has the charm of my NB. Much quicker and that's always fun but not really the point of the Miata. If you want Miata goodness but are a little bigger check out the NC miata's. More room for people and a bit more room for stuff. Fuel mileage in the new one is around 38 mpg as compared to 30ish in the 05 nb.

  • Fahrvergnugen Boyo boyo we surely LOVE the 95M we bought sight unseen (hell, I'd never even been IN one much less DRIVEN one) last year. What a treat these cars are! As for infotainment, I think the cassette and maybe the CD work but neither compares to the feeling of enjoyment.Mrs. F and I are both around 5'9" and slender and you're right; you don't DRIVE a Miata as much as you WEAR it.
