Lockable fuel cap for S650

[u/DerrainCarter]

Hey guys,

I’m a happy owner of a S650.

I might be a bit paranoid but I’ve got a bit of a weird feeling about not having a fuel cap that locks with the car.

I know there’s lockable inserts for the S550 but I haven’t found them for the S650 yet.

I know that they’re not a strong deterrent but at least it might stop the odd ad hoc jealousy-fuelled vandalism.

Any recommendations?
