yes you are right, until or unless there is no competition they will keep doing this, they dont let any company to settle down. the only threat to Cultus was Santro thats why suzuki guys introduced, VXL and VXLi (i for EFI) variants in Cultus, i was just amazed that how come PS could add Power Steering (HPS though), Power Windows (without power mirrors) and Stock Alloy RIMs to Cultus, it was a big big we could ever get from PS. and when PS launched VXLi version i was hopping now its the time, soon PS could even launch a Cultus with ABS but all in vain coz soon Santro went out of production and Suzuki Dominated the market again.
lets hope for the better if PS could add some safety and quality in their products
