I have to admit, this gave me a 1.21-gigawatt smile, even as I realized there had to be something wrong with it:
Legal matters, as it happens: the De Lorean went into production in 1981, which meant that stateside vehicles were cursed with the Joan Claybrook Memorial Speedometer, topping out at a meager 85 and highlighting the much-derided 55-mph speed limit. (For every good automotive idea the government gets, there are at least a dozen bad ones, and this was egregiously stupid.) Here’s a stock De Lorean instrument panel, as seen at Ask a Mechanic:
It gets more complicated. The speedo used for instrument-panel scenes in Back to the Future had a 95-mph scale.
And apparently the handful of right-hand-drive cars made did have proper 140-mph speedometers; in fact, the present-day De Lorean Motor Company will happily sell you a 140-mph speedo from presumed old stock for a mere $199. So the most likely explanation is that this is a real 140-mph De Lorean speedo with a bit of Photoshoppery, or possibly a new face for the old speedo, which can be had at retail, presumably altered slightly before installation. I can absolutely assure you that if I owned a De Lorean, I would have this done to my dash.
