OK, first we need to clear that there is NO comparision between Cultus and Liana.
Cultus:
* Built for small families.
* Large leg room back and front both.
* Great Resale value.
* Smart Looks
* Highly Efficient
* 20 year old technology
* Cheap maintenance.
* Little luxury.
Liana:
* Can be used for big family
* No resale buy if you intend to keep it for long.
* Newer technology.
* Better accelaration and handling. (Handling Cultus sucks even alto has lighter steering than it )
* Very opulent and luxurious indeed.
* Looks not so good
* Expansive maintainance
* Great security
* Efficient as compared to other cars in its sector.
Now we must understand that Liana is competetor with Toyota Corolla and Honda City and Cultus is small 1000cc smart car but in reliability, I will vote for Cultus. Infact we have our first cultus from 2005 still in our hands and is still fit after 150 K kilometers.
As for Liana, It will give you great value of money but remember many Liana engines have been opened by local mechanics and they have fingered with their engines.
