You may probably need to rent a car at some point or the other in your life, and it helps if you can rent it at a discount. There are plenty of ways to get discount for car rental. Obviously, if you need to rent a car, you need to know from whom you can rent. The best and most convenient way to search for car rental in Singapore these days is by using a search engine to find out about car rental companies in the area where you are headed.
Once you have a list of rental companies, find out what each is charging and compare rates. Call or email them about a price estimate if their rates aren't very clearly stated on their website. Most car rental agencies generally charge by a daily rate or a weekly rate. Go for a daily rate if you are renting for 2 or 3 days. Go for weekly rate if you are renting for more than 6 days. Weekly rate is usually lower than daily rate. Many rental companies have special weekly or weekend deals and some offer discounts to auto club members, army personnel, government personnel and certain corporate executives, so be sure to inquire/find out about all those.
Many companies providing car hire in Singapore display only their base rental rates to hook in the customers and then hook them with all the additional charges. So remember to check very thoroughly about all the extra expenses you are likely to incur. You will also have to pay for the car fuel if you are going for a prepaid fuel scheme, or you can choose to fill up at a local gas-station. There is an air-port surcharge if you are renting at the airport. If you're not renting at the airport and need to be dropped off there at the end of the renting period, the renting company will drop you off for a charge. If you need to rent extra equipment like a baby/child seat - and this is mandatory in some countries - the rental company will rent this to you, again, for a charge.
If you arrive at Singapore by air or train, it may be more money-saving to take the local transport to a local rental lot and take a car for rent Singapore rather than renting from one of the big car rental companies at the airport/train terminal. A local rental company will usually offer a better and more personalized service and may be more prepared to bargain with you over the rental rate.
Plan to book at least a week in advance, especially if you are travelling in a peak period or in the holiday season, car rental rates fluctuate as per demand.
Since you are renting for a day or maybe a week or two, there is no sense in going for the largest, most magnificent and, consequently, most expensive vehicle in the rental lot. Go for a small or what is known as a 'compact' car that meets your needs. This will come at a lesser rental rate. So you can save a lot of money by using these few methods.
