I agree with @Wanjiru above
If you can, please avoid Taxi/car hire espacially if you plan to invest via loaned cash. You might burn your fingers badly. And i always insist,if you will not personally be the one to run the carhire business or taxi..please think deeply before you invest,it's a tricky market!
Nevermind what haters say, ignore them til they fade away - Just live your life
