Wherever you buy, ensure you specify the car model/size precisely. I bought mine in the UK (so long ago I can’t now remember where, sorry) and although it was supposed to be tailored for a Légère it was clearly much too big.
I wouldn’t normally change the car to suit the cover but, now I have the 15/6 it is a perfect fit!
