Oscar,
Whilst I have seen AMG speedos which read to 300km/h, that is the first speedo and tacho I have seen which attempts to get around the problem of obscured instruments when a smaller steering wheel is fitted. Must admit, I don't go much on the look of it. As for the 107026 factory prepared rally cars, I'm unsure what instruments they had. The only interior photo of a factory rally car I can recall seeing was of one of the first 107024 (450SLC) cars which despite being fitted with roll cage and competition seats, was still fitted with a standard steering wheel (see photos I posted in the SLC rally car thread in the Articles section).
Des,
Going back to the link you posted, I am thinking that the replica rally car mods may detract from the value. Look at the asking prices in US dollars for these examples of the 107026 (500SLC) at
http://www.carsearch.com/Mercedes-Benz/1334.html and
http://cgi.ebay.com/ebaymotors/1980-Mercedes-Benz-500-SLC-Collectors-Car_W0QQitemZ110100238052QQihZ001QQcategoryZ6332QQcmdZViewItem Hmmm... Maybe I should see what I can get for mine overseas. Makes the price I paid look cheap.
Also interesting how a potential buyer needs to be aware of what they are looking at. Have a look at
http://www.dima.ac/carsforsale/Album18.htm for someone attempting to sell a 107024 (450SLC) complete with hideous US bumpers as a 500SLC.
