My previous 3.5L Toyota Prado I was doing 5.71KM/LT
3.2L ML320 I was doing 6.12KM/LT
3L Toyota Alphard 6.6KM/LT (My is very sporty/mean looking and looks way better than a XC90 or Mazda 8 )
My friends have said I only have two speeds in brain when I drive, STOP / GOOOOOOOOO I burn fuel fast
Each driver is different, you could probably do more than 10KM/LT on each of the cars that I had previously if you are a nice/safe driver.
The only major problem with the GDI Pajero that everyone talks about is one of the pumps, cant exactly remember which one it is but once it dies costs like 6K new, cheaper for 2nd hand. That is the only problem I have heard of the Pajero. Also as petrol prices are going higher and higher, most locals dont want the big heavy SUV vehicles and that is why the price looks cheap.
