Ive seen other sheets like this
Infact i imported for a friend 5 A Grade Vitz with a W1
And many times i see 4.5 Grade Prados with 2 parts W2
Grades r not directly proportional to body touch ups
Also due to low mileage maybe its graded
Or maybe its the car is of some friend of the auction appraiser
Get the point ???
