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 ..
