If you can afford an LX 570 then obviously go for it! But it costs aorund 1.5 crore and drinks petrol like a thirsty man goes after a glass of water. It is a better SUV though!. still, If you want to buy an LX 570 wait for another two years till it's used cheaper models are available.
Infact leave the Lexus LX and Amazon . For the amazon money you can buy a used Range rover 2004-2005 model and it's worth the money!!!!!
You can get climate control seats, Harmon kardon 14 speaker system, 4 zone climate control, more speed and aceleration, beter to drive in the city the only problem is that it's about 70% of what the landcruiser is offroad!!!!!!!!!
