Locking gas cap

[vonhazelwood]

Can anyone tell me if there is a locking gas cap available for a 1985 280i?

I've been looking for a gas cap for my 86, preferably a locking one so if you find anything let me know!

I have been trying to find one for ages..I think the original were from motorcycles..I was thinking of changing mine to this type that has to be fixed to the top part of the filler neck..The cap also needs to be Non-vented.

Mine is very similar to this...Push and turn.
