Option 1:
-Save the 1M and buy the car on cash basis.You forgo any returns on the 1M.
Option 2:
-Take 1M loan from bank for 4yrs @24%pa.
-Total interest after 4yrs is 564K ie 11.7K/month
-Monthly loan repayment (includes interest component) is 32.6K
-Invest the 1M on 4Yr TBill at say 13%pa = 10.8K per month return
-Thus net interest expense is 11.7K-10.8K=900sh
Option 2 makes mathematical sense right? Emotionally though you will be very stressed if you don't have a high income.Paying 32K plus rent plus parking plus fuel plus maintenance and spares plus insurance for a depreciating jalopy is no fun.The Option 1 guy is at more peace. You decide.
Formally employed people often live their employers' dream & forget about their own.
