The number of imported cars in Vietnam rose 61 percent to 129,733 units in the first 10 months this year.
Passenger vehicles saw a rise of 50 percent to 90,029 units, according to Vietnam Customs.
In October, the three major import markets were Thailand with 8,320 units, followed by Indonesia, 3,925, and China, 1,733.
Over 11,700 cars with nine seats or less were imported to Vietnam last month, doubling from September.
A media representative of a Japanese auto brand said the rise came as customs activities resumed after months of social distancing.
Companies were also importing more vehicles to prepare for the end-of-year shopping season.
Vietnam also imported $4.07 billion worth of car parts and equipment in the first 10 months, up 33.5 percent year-on-year.
Sales of imported, completely-built units rose 24 percent year-on-year to 97,028 in the first 10 months, according to Vietnam Automobile Manufacturers Association (VAMA).
