if you high speed all the time... petrol better

diesel is not free revving... need slightly different style

diesel vs petrol reliability is not really an issue... diesel may be better but you don't see petrol engine fail everywhere right?... imho not a big deal

lc is a toyota icon... lemon car aside... wont put crappy engine in it.. if you have long trip... better buy early to give you time to work out any kinks...
