2013 RX 450H parcel shelf

[Vanhoussen]

I’m trying to find a rear parcel shelf for my MK3 RX 450H but seems the MK4 cover is much cheaper.
Does anyone know if a MK4 rear parcel shelf cover will fit a MK3

It won't. Different mechanism of attachment altogether

When I bought my 3rd Gen RX450h from Lexus Cheltenham the pull out cover, flexible shelf or however you describe it, was lying diagonally under the hatch.  When I arrived home I attempted to fit it but without success. I then closely examined the item and noted a small label on it marked  'Honda'.  I can only conclude that whoever cleaned the cars had transposed the part between a Honda and my Lexus.  Anyway, Lexus sent me the correct one and didn't want the Honda one back, so I must put it on eBay.
