If you stay in Vancouver for less than 12 months, renting a car or a short-term lease is the cheapest way to use a car. Compare the cost of buying a car and renting one, if you buy a car, you must pay the purchase price + tax + insurance + maintenance + repair (may be involved). If the car is sold within half a year, the depreciation cost of the vehicle will also be included. If you rent one, you only need to pay the rental fee + tax + insurance. The rental company is responsible for the repair, maintenance, and damage of the car. Also, there will be so many cars you can choose, and the time of car use can also be flexible, saving you many times and unnecessary troubles.
If the rental period exceeds 3 months, you can also do a short-term lease, thus the rental price and insurance will have more discounts if you are doing lease.
