Should be so long as they are clocks from the same car as yours (GTI 8V or whatever it is) and they work in the first place. Obviously you will have the milage that was on the scrappy car though. Have a look on egay as there may be some with similar milage to what yours is currently on. Dont be tempted to get ones with much less milage without declaring it when you come to sell it though, and may be worth informing your insurance company. Not entirely sure if the insurance company would give a toss, but it kinda covers you, as VOSA will have all milage for your car recorded at MOTs, and if it gets recorded as less than the last time round, you could find yourself on the end of some unwanted questions.............
