Buying a car is one the worst decisions a young man/couple could make, that is unless they have alot of resources. The costs associated with ownership are immense and that money would rather be used elsewhere to secure the young couples financial future.

So lets assume he buys a car, then these will be his costs every year:
-purchase price (subaru, premio, golf etc) = 1.2m,

Costs:
-Interest on car loan @18% = 216,000
-insurance at 7.5% = 90,000
-fueling @ 700bob per day, 5 days a week = 182,000
-parking fee @300 bob a day = 81,000
-car depreciation = 400k per year
-servicing 4 times pyr, @10000 = 40,000
-spares = 40,000
-tyres (2 per yr) = 30,000
Total cost = Ksh 1,079,000 per year.

For 3 years of ownership that will be a cost of Ksh 3,237,000, an amount enough to buy an apartment (hapo mombasa road) cash. And the car will be worth just 450k. There are better ways to invest such cash instead of literary "burning it inside your car's 1500cc engine".

If that stupid girl had advised her new husband to buy appreciating assets like land or stocks lets see hjow the situation would be:

So instead of buying car, buy stocks or land kitengela 1.2m. Also, instead of using 1,079,000 on car every year, use the money to buy more land, thus 3,237,000 bob land after 3yrs. Therefore after 3yrs total assets will be 4,437,000. And the land will be appreciating at 30% each year i.e 1,331,100 pa.

In conclusion the one who buys the car will have an "asset" worth 450k after 3 years, while the one who chose to invest elsewhere will be having assets worth 4.3m, which are appreciating by 1.3m per year. So the choices that one makes early in life have very serious consequences on our future financial well being.
