Hello there Cavalex,
As per the website instructions, on 4th March I emailed my wish to pre-order 4 in "Lafarge" iivery. I have not yet received any acknowledgement; perhaps this is the norm and I shouldn't be so impatient, but it would be comforting to know that my request has been received and recorded.
CADs look fantastic and I hope this is able to get the go-ahead very soon now.
Best wishes,
John D
