gearbox is not normally noisy, small scratches can be polished out and the sun visors cleaned
get it back and say you want it valeting, reversing sensor wires - tie wrap them out of the way, the will connect to a reversing bulb so you could pull them up into the boot/rear
small glitches except the gearbox

ps. change the wheels when you go back, they will try and blame them any excuse
