Tony Turbo's had a black washer bottle. Not really sure what the deal was there. His car is on an 'E' plate.

I have two washer bottles left over from mine. One is the original 1989 one, the other is what I know to be the proper 90 spec one (practically brand new) and the one I would choose. The neck sits nicer in the engine bay. Both of these fitted my car without any issues.
