These are the differences in LIANA SPORT:
15 inch alloys with 195/55/15 Brigdestone Turanzas
Different front grill
Different front bumper with extensions
Side skirts
Suzuki Sports stickers on back doors
Lip spoiler on rear trunk
Different rear bumper with diffusers
and
ABS brakes (not sure whether these are available on standard model though!)
I think that is a lot for a small increase in price! I like the ABS option best.
