Only problem with the water pump was that it was mounted too high, lose an inch or three of water from the rad and you are pumping fresh air so I would have to say shame about the idiot driver for not noticing and stopping to investigate.
Heads only tended to warp if the driver was stupid as above.
Antifreeze stopped the corrosion of the head studs to the heads so the heads would lift off easy as pie. Again down to the stupid driver to get this bit right too.
I think it's about time Daimler got themselves a decent European Designer - after all it is a European company and people are buying it to have a Euro...
