ppl nowadays usually look at badge,size,appearance when buying a car,what's underneath was not so significant from what i can see.

rush is base on avanza with prettier skins,it is an expensive way of buying an avanza,but ppl don't see that

nautica is base on daihatsu terious,a car for british market,has different underpinning from the rush/avanza,has different drive system (4wd),different interior(exactly the one you get in terious),shorter wheelbase means will be nimbler arround town, but all in all ppl see the skin and forget the substantial.
