2000 USD car and what could be alternative usages of it, while we were discussing this somebody suggested that why cant we buy car and get them joined back to back. it will save all the pain while parking and taking reverse direction, just get down and start driving from other end.
after buying 2 car your expenses will remain much lower than buying any other car.
2000+2000+50=4050, 50 USD for getting it joined by towing end. your car will be having capacity of 10 people.
some of more use we could think of
. Get rid of doors and use as Indian auto rickshaw.
. Get big offroad tyres and use it for farming purpose.
. Connect as many as nano and you got the nano train.
many more to come..........
