i had ride on my friends FL Sigma, interior was disappointing as its same as Pre-FL but somewhat seats felt more cushioning and the screen is bigger with android auto. Also the owner have Pre-FL Fortuner and he think the suspension has been improved but i found slightly better. Engine noise has decreased and the power/torque is great even on lower rpm. Overall i think its fine, those rims is not my taste as i found it bit dull plain design.
I hope Indus bring the Legender Fortuner model with different interior color and the rims.
