We passed on the "Finishing Touches", they were a rip-off. EG we wanted to upgrade from a white oven to a stainless steel one - upgrade cost: £600
Cost of a new stainless steel oven at Currys: £600 (£100 more than a white one).

So we decided we'd keep the default, put the original oven on ebay when we wanted to upgrade and just buy and install a new one ourselves. Then we got a call from the developers a few days before we moved in: "they've delivered the wrong oven to us by mistake, if we send it back then we'll have a delay on finishing the build. Would you be OK if we install this stainless steel one instead of the white one you ordered?"
