i think the guy asked about rental cars :o and did not say that he is going to use the pulic transportaion .. which we all agree is a real mess :S

i am currently renting a car from first rent a car its a small one Mitsubishi Lancer ..
2006-2007
fairly in a good condition costs QR 1700/-

until u get your car shipped i think its gonna be a good solution ... unless u r thinking of something larger like an SUV
