How are the cars, jeeps, vans, minibus and coach like in Vietnam? Are they safe?

Our standard of vehicles we use for travel & tourism must be new and not more than 5 years old. This is not only for your comfort but also for environmental protection. There are four main vehicle types being used now: Toyota, Mercedes, Ford, Honda, aside from these we sometimes use Nissan and BMW. For those who have traveled to Vietnam in the past may remember the old Russian jeeps used for the Northwest and Northeast loop. We have stopped using them because of safety and environmental reasons.
