It's all about condition with an old car. The Kingswood isn't a particularly valuable classic car, unless it's in good condition with low miles on the clock. Your uncle's seem to fit that bill. If you go by the trade value it's worth around $2000, but to a Holden enthusiast or someone looking for a cheap classic to enjoy it could worth $6000-$8000. It might be worth showing it to one of the insurance companies that provide cover for classic cars and see what insurance value they would put on it. You'll also find more details on the pricing & specs here.

Another reader has told us that Jamie should be able to find what he wants at Holcar in Lilydale (ph: 9739 6088). If that proves unsuccessful, Peter Simpson says he's got a sticker that might suit in his collection of old speedos and might be able to help out if Jamie cares to contact the Cars Guide office again.

Metric conversion scales for speedos were popular at the time we changed from imperial measurements to metric, but I haven't seen one for years. I'm told Auto Surplus (ph: 9873 3566) and Auto Spares Galore (ph: 9758 3644) used to stock them, so it might be worth trying them. Other than that, you might keep an eye out for one at a swap meet. As for a new speedo, I don't believe there are systems available for the HT. One solution would be to make your own scale by applying a strip of tape to the speedo face at the appropriate speeds -- 50km/h, 60km/h and 100km/h.
