Option 4 :
Generally we change all our cars at intervals of 5 years/ 50k kms ..
but off late change happens every 2 years or so..
Rapid - Sept 2013 to August 2016 - 42k km s
Civic - Feb 2014 to November 2016- 34k kms
Oldest car now is the 2012 verna driven about 25k kms.
I guess its best to sell the car when it starts bleeding you of your money or when your bored and have found another love
Mostly we end up finding a new love to romance ..
