Patina

[GREG]

Can someone please explain to me the difference between worn out and "Patina" when referring to areas on a car ?

I often see leather that looks knackered to me but owners delight in saying they are looking after the natural patina. Same goes for woodwork but not tyres and paint but not pistons. I guess there is a fine line but not many would sit on a musty sofa at home with holes in it ! apart from me :-)

Greg - old but good patina
