Of course Heinz and Zallium you're both right. This will be my third Morgan and the third with wire wheels. I just prefer the look of steel wheels but there is a very real limit to funds available and there will be no hurry to change them. I would have maybe gone for the black wires but I absolutely refuse to pay £850 to specify black over silver, especially when an after market set can be bought for that amount!
More pressing for me at the moment is that they've still not got around to starting my car so talk of changing wheels is getting a bit ahead of myself !
