If you don't need the bigger cargo space of the L200 get the Vitara. If you could swap the Vitara's engine for a Toyota 2C diesel it might be also a good improvement.
Yung Vitara malakas sa gas eh, lalo na kapag matic tapos hindi pa malakas ang makina. OK nga yan if you are able to find a good diesel engine swap. But Toyota 2C's are known for having reliability issues diba?
Depends on your priorities. If you really need 4x4 and want to go off roading then it's the Vitara, otherwise, keep the L200. More efficient, more parts, and when you give it a nice coat of paint and nice rims, still looks good.
