How accurate are the grades?

The overall grade given to a car is based on the auction inspectors opinion of the car, it is not an exact science and takes into account the cars age. Due to the experience of the auction inspectors 9 times out of 10 a grade will offer an accurate representation of the car. However as grades are subjective a car which 1 inspector may grade as 4 another auction inspector may grade as 3.5 therefore especially with older cars, it is important to look beyond the grade and focus on the condition report.
