First of all, all cars are based on new car purchases.
The Santa Fe K5 is average, and the Grandeur is above average.
Next, E Class and 5 Series are in the top 10%, and S Class and 7 Series are in the top 1%.
The funny thing is that both AIs rank used cars with more than 150,000 km or more than 10 years of age at the lowest level haha.
