You can usually hire a car from two sources, large multi-nationals, or local companies at your destination.
Multi-nationals. Some do not run all their car rental services themselves, they often franchise out to local companies. Also many do not have a central UK emergency helpline number to contact, so in many countries if you have a problem you will be forced to deal with the office where you collected the car. They do have advantages if you are driving long distances because in case of trouble you can usually obtain a replacement car from a different office.
Local Car Hire. Can be cheaper but cars may not be as reliable and you are on your own if you hit problems. Can be good for just local driving and if you only need a car for only a few days.
Shopping around is essential because prices are always changing and be flexible with your requirements. Don't be afraid to negotiate. Make sure that you carefully state your required specifications to ensure that you are comparing like for like quotations. Does your quotes include unlimited mileage, and adequate CDW (Collision Damage Waiver)? Are the insurance excesses comparable?
You will require a valid driving licence and at least one type of other ID for each driver. For countries such as India, Japan and Egypt you may also require an International Driving Licence. The AA and RAC can supply them. Age limits vary, in the USA and other countries, under 25 year old's cannot hire a car. Most car hire companies also have an upper age limit.
Check all documentation from the rental company carefully, reading the small print is absolutely essential.
Do your research before you travel, make sure you know national speed limits, and which warning triangles you must carry. Check child seat requirements for babies and toddlers. Make sure you are are aware of instant fines etc.
