Benchmarking

In the first case i would suggest him to buy a HYUNDAI i-20 why because this is economical for his family interms fuel cost and mileage 

The second one mentioned below,

Bench marking is the standard of automobile industries involves  in  a structured comparison between similar product ,services and process to justify the performance of the product to meet the customer requirments

benchmarking is a process in which change its false parameter without affecting its nature  (remove all the negative from the old version )

This is plays an important role  at competitor  whose budget price we can evaluate in order to give our best product interms of design level and OEM

It  is based on the product feature and  perfomance  specification of the designed OEM  product to implement  within the plant
