Where do you intend to buy the car from?
In Kenya or import one?
Where are you based for the rest of the year?
Are you based somewhere you can source a vehicle?
1. You can buy a car with the intention of selling it within two months you're in Kenya. ...and do this every time you travel to Kenya. There is a possibility of selling it at the same value you bought it or at a higher value.
2. Buy the car use it for the two months store it for 10 months. When you return to Kenya (depending on what car it is ) you may need to have some work done... new battery, water pump etc. & also consider the car will devalue each year.
3. Buy the car and give it to a relative/friend to use + service it and make it available for the 2 months you're in Kenya. Car will also devalue.. Or your rela may 'lose' the car.
no.1 is a win-win situation.
