Hi Lee. Really nice car you've got there. I must admit that at one time i wasn't that keen on sierras. A mixture of my age , not thinking they were a proper classic ford as they were a strange shape, and the fact that the xr4i replaced the capri. Over the last couple of years though they've really started to grow on me. In fact i recently bought a xr4x4 for my wife.
