There are two types of car insurance cover. First is the "Third Party" insurance which is mandatory for all vehicles on the road in Qatar. The charges for this I believe is fixed by the authorities and are the same whichever insurance company you choose to get insurance cover for your car. The second is the "Comprehensive Insurance" cover where prices vary from company to company. To get the cost of "comprehensive insurance" I suggest you visit some insurance companies, email them or call them. You can get their contact details through Google. Just for your information, many insurance companies do not like to provide "comprehensive insurance" to cars which are more than 5 years old.
