Do not buy cultus, celerio is launching next year as its replacement and celerio is way ahead in tech from cultus therefore cultus owners will not enjoy same resale in future as they used to.
WR is a very good option but if you do not like it do not buy it either. Better to buy 2nd hand Alto at this time and wait for 1 year to get celerio.
Someone above said cultus runs economical yes it is but WR runs more economical. My WR In 25k kms running, never went to mechanic and i saved at least 20k -25k in fuel consumption in 25k kms running as WR is more fuel efficient than cultus.
