does the spare wheel come with a centre cap? Doesn't look mine does, any ideas how much they cost?

If the spare wheel had a centre cap in it how would you bolt it down?

No they dont have one.

thats a good point, I guess they could have left one with the wheel jack? How much would a New one cost?

The idea is you poke the one out of the wheel you take off and swap it over. IIRC its a couple of quid for a new one.

i ordered a second hand one of ebay then stuck on a new sticker in the middle, not quite as new but looks ok.
