Dacia is just a cheaper version of Renault cars. so really when buying a Renault you getting a bargain as same engine etc, the difference is the cosmetics which are cheaper.
Ie you know for example the Dacia Sandero Stepway
look at the same car (i believe) in South America...look at the badge.
Dacia Duster:
Renault Duster
this is just to open the eyes of many wanting to purchase a car and saying I don't want Dacia as is cheap will not perform well etc...well it will perform the same....but you right it will be way cheaper and yes the plastics and feel of the car will feel cheaper but on what it matters it is still a renault engine exactly the same as the ones on the Clio, Capture Kadjar etc
choose wisely
