In 2026, the used car market in Thailand will be more volatile than ever. With the aggressive price cuts of Electric Vehicles (EVs) throughout the year, the residual values of Internal Combustion Engine (ICE) cars have fluctuated significantly.

If you are planning to sell your car, simply guessing the price is a recipe for disaster. Set it too high, and it won't sell. Set it too low, and you lose money. Here is your guide to accurately estimating your car's value in the current 2026 market landscape.

1. Understanding the "Price Gap" (The Golden Rule)

Before you check any website, you must understand the difference between "Asking Price" and "Buying Price."

• Retail Price (Asking Price): This is the price you see listed on websites. This includes the dealer's profit margin, vat, sales commission, and refurbishment costs.
• Trade-in/Buying Price: This is the cash amount a dealer will actually pay you.
• The Reality: Your car's trade-in value is typically 15-20% lower than the lowest listed Retail Price of the same model.

2. Key Factors Affecting Value in 2026

Not all cars depreciate equally. In late 2026, these factors matter most:

• Powertrain Type:
  • Japanese ICE (Toyota/Honda): Prices remain relatively stable due to easy maintenance.
  • Early EVs (2022-2023 models): High depreciation due to new cheaper models and battery health concerns.
• Mileage: The psychological barrier in 2026 is 100,000 km. Cars under this limit command a premium (High Grade).
• Warranty Status: For EVs and Hybrids, having a valid battery warranty is the #1 factor for price retention.

3. How to Calculate Your Car's Value (DIY Step-by-Step)

Step 1: Benchmark Online

Go to major listing sites (see references below) and search for your exact year, make, model, and trim level.

• Find the lowest price listed.
• Example: You have a 2020 Honda City SV. The lowest listing online is 450,000 THB.

Step 2: Apply the "Dealer Margin" Deduction

Dealers need room to fix up the car and make a profit.

• Deduct 10-15% for popular cars (City, Vios, Isuzu).
• Deduct 20-25% for niche brands (Mazda, Ford, Chevrolet) or luxury cars.
• Calculation: 450,000 - 15% = ~382,500 THB. This is your estimated "Trade-in Value."

Step 3: Adjust for Condition

• Deduct for needed repairs (worn tires, scratched bumper, torn seats).
• Add (slightly) for low mileage or full service history. Note: Aftermarket mods usually do NOT add value.

4. The "Middle Price" (Rad Book/Blue Book)

Financial institutions use internal "Red Books" (standard prices) to determine loan amounts. While these aren't public, you can estimate this by asking a bank: "How much can you finance this car for?"

• The Selling Price is usually close to the Finance Amount. If banks lower the loan limit for your model, the market price drops immediately.

Conclusion: Guesswork vs. Data

Checking prices manually gives you a rough idea, but market dynamics change weekly. A price you saw last month might be outdated today.
