Re: Mileometer Adjustment on the 156?
Davie, two tips for you:
1) Did you ever watch Ferris Bueller's Day Off? Put the front of your car on axle stands, jam the accelerator down, let the car "travel" 989000 miles, and you will have removed 10000 off your mileage. (Tips - this will be quicker in 6th gear, and don't let the car fall off your axles stands and drive into your dad's pool like in the film)
2) The above may use a lot of time and petrol, so why not just drive everywhere in reverse, until your mileage is low enough, then start driving forwards again?
