I can't see why MMC would not be able to build you one with the correct 5-stud hubs for steel wheels, why not ask a dealer to enquire for you? Also with those hubs you could have minilites in the correct 5.5x15 size instead of steel rims - light, easy to clean, no rust potential and look great IMO.

The 70th anniversary 4/4s all had steel wheels with chrome disc hubcaps, and a folding windscreen with the 9-stud traditional hood. When I was buying mine in 2007 every dealer seemed to have one so I saw a lot of them! They had a 1.8 Duratec with a little more power than the 1.8 black top Zetec, and the dash layout is similar to the latest cars. The 75th anniversary version also has the traditional 9-stud hood, but a fixed windscreen and the 2-litre Duratec from the Plus 4 as mentioned above. Personally I much prefer the newer type fixed screen and easy-up hood, which would rule these two versions out for me - others will disagree!

However I find my S/S wires easy to clean! I just use "Muc-off" spray (sold for mountain bikes), spray on, leave for a minute, then blast off with a hose or pressure washer. I've never had to do any other cleaning in 4 years, except once when I had the wheels off I cleaned the inner side too. This was the reason why I changed from chrome wires to S/S.
