1). Is it an auctioned vehicle?
I recently sold a friends 2003 Toyota Land Cruiser Cgynus, black, 2003 KHI registered. It was a brand new import back in 2003. Single owner, very good condition, 70,000Kms driven. It had everything in it except Night View and the Mark Levinson premium sound system.
Sold it for 60,00,000.
If this Cgynus is exactly as you have mentioned it to be, a good offer for it would be around 68,00,000-72,00,000 provided that it is not an auctioned vehicle.
2). The fuel consumption isn't that bad considering the fact that the power plant is a 4.7L V8 which chucks out 270 horses. 6-7KM/L is what it gives in intercity driving. On the highway it should give you in between 8-9KmL at maximum. These calculations are based on a well maintained vehicle.
3). No, there aren't any current Navigation software programs in Pakistan that would support the Navigation systems of JDM vehicles. If you really want the language change then get yourself a USDM or EUDM LX470 Tv/Navigation unit. All the functions in them are in English.
4). Can you please elaborate 'up and down'.
5). The Adaptive Variable Suspension system (AVS) in the LX470 has two options. Sport, comfort and normal mode for the shocks. And low, normal and high for the ride height. Now, sport mode hardens up the suspension for a stiffer ride. It's basically used when you have a big load in your vehicle. It works great while off-road as well. Comfort mode is used mostly for basic everyday, relaxed driving.
