I had a Cultus 2004 previously and now I have a Vitz 2004 import of 2007.
In terms of Genuine parts cultus is more expensive.
For example: Genuine set of Disc Pads of Cultus are around Rs. 4,500 and I just got the Disc pads on my Vitz changed for Rs.2,800
As far as the running cost goes there is no way cultus can achive the millage of even an auto Vitz.
My cultus used to do around 9 Km/L where as Vitz is doing around 12.5 Km/L with AC switched on at all times.
There is no comaparison between the two cars. Vitz is far Superior to Cultus.
