The standard of vehicles across Vietnam and South East Asia varies between countries.
In Thailand & Vietnam, the quality of vehicles is more modern. They offer new models equipped with air conditioning, seat belts, and comfortable seating. Luxury cars such as Mercedes, BMW or limousines are available for hire but an extra charge will be applied (if any).
In Myanmar, Cambodia, and Laos, the level of development and tourism is lower than elsewhere in the region, therefore it is necessary for you to lower your expectations of the vehicles. The models are generally older and sometimes they may not be equipped with air conditioning, especially in more remote areas. Wearing a seat belt is not common practice in these countries and be aware that not all the vehicles in which you travel will be fitted with seat belts.
