One of our members suggested that one should not buy a car worth more than 50% of annual household income. Most of us widely accepted it as a thumb rule for sound financial stability. To start with, my present car is much more than 50% of our household income.. . Those do not want to tell the %, just join the poll as it is confidential! You may do one SK and one pre-SK series cars. Just to give an example, if my car is 100k, and household income is 200k. then the percentage is 50%
