They are coilovers as standard on the MBs,tell them they are just uprated gas shocks<which they are> =£10
Nothing special about them + cheeper than oem units to replace all 4 corners.
A classic insurance company also told me the Mc2 are not of the Classic type as yet btw .
Mileage wise its the same cost for me 5k or 14k PA get them to alter and compare on the phone for best results ect
ps Putting the cat back and getting another MOT on the MC as the maybe buyer has had long enough to view.
So another year to use it and get it mapped for a little better mpg,
