i got it from asm autos in thame (not far from me) they said they'd tested it and it worked and came wih 30 day or 90 day warrenty (cant remember how long now :cry). got it home as rear subframe was off so couldnt drive the car. plugged it in without bolting it up and it worked. also came off a newer car than my w reg and looks cleaner than all my oe locks
