from wat u state... i assume ur suzuki swift is 1991's model? is
auto or manual? if its manual remember to check the
gearbox...
try starting the engine, and open up the bonnet, and see the
engine, does it vibrate abruptly, i suggest u dun buy if the engine
vibrate abruptly, it means tat the engine is unstable.. hear for
any suspicious or unwanted sound....
