Fuel average depends on whether its diesel or petrol. Petrol V8 gives 5-6 in City, don't know about 4.2 Diesel variants. Price totally depends on condition and model year, late models (2005-2006) ones can be seen for 7-8M which is very high. You can find the pre facelift 1998-2002 ones for 5-6.5M easily. Remember that some owners have converted their regular Diesel models into Cygnus and some have body changed or changed the interior into the later model zigzag gear wala which came 2003-2007 and Oh, some fankaar have even changed Toyota logos for Lexus logos to give an impression that it's LX470 and not an LC.
