I'm thinking about the seller that sold me a truck many years ago...
I asked for seatcovers, and he rejected to give me any.
That made me a kind of angry until he said:
No Sir, it's not you that shall cover up the nice looking seats, you pay big money, and it's you that shall have the pleasure to make it worn.
Next owner will get the seatcovers for free.
I think I'll use the 'plastic fantastic' as it is, just as I did with the other keyboards.
But, I'm cover it up with dustcover when not in use.
