For CVT owners out there, during CVT oil change, insist not to use normal ATF fluid. May damage your CVT gb.
add in some more: tinted headlamps, crystal rear lamp + leather seat. And the best thing is still cheaper than premium LB 1.3
What to write about.. I had test driven both cars and simply put:
FC wise, LB wins hand down.
Looks - subjective, to me LB is fugly... just my opinion though. FLX a bit weird when it first came out..getting used to see it on the road i guess 
Equipment and specs - on par if compare premium LB with executive FLX.
Price - FLX, full spec still 5k cheaper than premium LB 1.3.
Driving, ride and handling - FLX. City driving LB, because of the light steering, feels very
space - FLX

In conclusion, you will buy LB because of either due to FC/ LB fan/ skeptical with Proton quality. FLX, best bang for the buck.
