Blimey that is well expensive!
You can get a set of trays which is the one you want and the one that goes in front of the cup holders under dash for £11 from the dealers.
They are advertised all the time on ebay and for some reason people pay £20+

I have them and the front one is handy to just chuck keys/coins into but as already mentoined the handbrake one is pretty pants as anything too big fouls the handbrake.
