I brought one off Ebay from Germany and they said it would fit a RHD E55.
Most of the boot protector fits perfectly however the right hand bottom corner for some reason does not quite fit.
I managed to fold/angle it in slightly,but it does stick up slightly.
The larger engined cars in the 210 range have bigger fuel tanks and therefore have a slightly smaller boot, I think 70 ltr and 80 ltr respectively. Not sure about the 211 though....
