A cheap car rental in Ho Chi Minh City is going to be a problem. The thing is, you simply won't find one. Why not? Because you can only drive in Vietnam with a special Vietnamese license. An international driver's license is not valid here.
That's why renting a car in Ho Chi Minh City without a deposit is only possible with a local driver. Renting a car will cost around VND500,000 - VND10 million per day (depending on the class of car you choose). Driver's services are paid separately - from 400,000 VND for 1-4 hours per day. Thus, the total price of car rental in Ho Chi Minh City starts from 900,000 VND.
A personal driver is certainly a plus. He or she knows the ins and outs of traffic, free parking spaces, inexpensive restaurants with national cuisine, and other trivia known only to locals.
A 24-hour car rental in Ho Chi Minh City is available at the Tan Sonnyat Airport building.
A great and cheaper alternative to renting a car in Ho Chi Minh City is to rent a motorcycle or scooter. The approximate cost of such an "iron horse" is 200,000 VND per day. But be prepared for huge traffic jams on the road and chaotic traffic. Vietnamese drivers are not very well-mannered on the roads, constantly honking for no reason at all, failing to pass pedestrians, and often violating traffic laws.
