I just wonder if someone could possibly give me advice? My dark blue ( indigo) Toledo TDiSE which I bought new at the end of 1999 from SMC Exeter has and still is a fantastic car. Always reliable and not even a rattle out of it after 123,000 miles. I know it could actually do three times as much milleage. I always keep it in excellent condition and it is protected by decent polish under the dirt. I use Wonderwheels on the alloys and am well pleased. For some time there seemed to be a bubble on the alloy on one of the alloys in the rear. I didn't over use the Wonderwheels. Suddenly that bit of alloy which had the bubble dissapeared. So the bear metal on that large enough patch has no alloy covering it. I actually think a chap with a hand held wash hose did the damage. The pressure of the hose rocked the car. When I moved house, I suddenly had no outside tap, so I got it washed by a chap with a pressure hose for a while. Unfortunately anything to do with alloy wheel repairs costs a fortune.
