Why do people say, “You should avoid buying a used Aqua?”
The Aqua boasts high popularity in both the new and used car markets due to its excellent fuel efficiency and compact body. However, due to its popularity, there are many cases where vehicles in poor condition or with high mileage are traded at high prices.

Points to note when purchasing a used Aqua
Thoroughly check the condition of the vehicle
The most important thing when choosing a used car is to thoroughly check the condition of the vehicle. Be sure to check carefully for scratches and dents on the exterior, as well as the dirt and wear on the interior, the condition of the engine bay, etc. If possible, it’s also a good idea to check the maintenance records to find out about past maintenance and repair history.
Hybrid system battery status
Because the Aqua is a hybrid vehicle, the condition of the battery is particularly important. Battery deterioration not only directly leads to a decrease in fuel efficiency, but in the worst case scenario, it can result in expensive replacement costs. Before purchasing, have your battery diagnosed by a dealer or other professional to check its remaining lifespan.
Mileage and price balance
Mileage is one of the important indicators for judging the condition of a vehicle, but a low mileage does not necessarily mean that the condition is good. Vehicles that are driven short distances may be more likely to put a strain on the engine and battery. Carefully consider the balance between mileage and price and make a comprehensive decision.
Choosing a dealer
It is also important to choose a reliable retailer. Check the after-sales support system and warranty details, and choose a retailer where you can make a purchase with peace of mind.
