Why are used BYD S6 cars so cheap?

[Bryan]

BYD S6 used cars are inexpensive primarily because their engines and transmissions are independently developed, resulting in lower costs and correspondingly lower prices. Here are several valuation methods for used cars: 1. Time-based calculation: Annual depreciation = original value / expected service life. For example, a 100,000 yuan car with a 10-year expected service life would depreciate by 10,000 yuan annually. This means at the end of the first year, the car's value is 90,000 yuan; at the end of the second year, it's 80,000 yuan, and so on. 2. Mileage-based calculation: The "54321" method. Generally, American, Japanese, and German cars have an effective lifespan of around 300,000 kilometers. Beyond this, maintenance costs may exceed the car's value. Divide a car's effective lifespan into five segments of 60,000 km each, with each segment's value being 5/15, 4/15, 3/15, 2/15, and 1/15 of the new car price respectively. 3. Formula-based calculation: Current price of the evaluated vehicle = replacement price (current new car price) × (1 - years used / specified service life) × 100% × adjustment factor. Here, (1 - years used / specified service life) × current new car price.

It's quite normal for the BYD S6 used cars to be cheap, mainly because the brand's early reputation wasn't that great. I've helped friends check a few, and found many have minor issues like easily aging suspensions or strong interior odors, which are costly and time-consuming to fix. On the other hand, this model had high production volumes back then, leading to abundant supply in the used market, naturally driving prices down. While BYD's new cars have improved significantly now, the S6 is an older model with outdated technology, making many young buyers prefer adding a bit more money for a more reliable SUV. Rapid depreciation is also key—it loses value quickly after a few years, especially with high mileage from long-distance driving, leaving big room for price negotiations. Always test drive and inspect the frame and engine condition before buying used; don't just impulsively order based on the low price.

Having worked on many S6 models, to be honest, the reason they're cheap lies in their common faults. Issues like circuits prone to short circuits and overheating, slow turbo response, etc., occur frequently, leading to high repair costs that drag down their second-hand prices. BYD's quality has improved significantly over the years, but during the S6 era, the material quality of parts was average, resulting in noticeable noise and less-than-ideal fuel efficiency. Used car dealers offer very low prices for them, and buyers naturally haggle more due to concerns. High-mileage cars show obvious wear, and loose chassis support is a common problem. It's advisable to conduct a comprehensive inspection before purchasing.

I've bought and sold several used cars, and the low price of the S6 is mainly due to high supply and brand bias. The pricing of new cars wasn't high back then, and the depreciation curve is steep, possibly leaving only half its value after 5 years. Consumers are much pickier now, disliking the S6's outdated design and less practical space utilization compared to the Haval H6, coupled with the rise of BYD's new energy vehicles, making the fuel version even less popular in the used market. Market psychology looks down on it; well-maintained ones might be worth something, but most are dragged down by poor upkeep. When purchasing, pay attention to the year and avoid cars with accident history.

As someone who follows automotive technology, I understand that the low resale value of the S6 is due to rapid technological advancements, leaving older models struggling to keep up. The engine efficiency and emission standards of the S6 are significantly inferior compared to newer models, and its electronic systems are simplistic or even laggy, prompting buyers to prioritize more fuel-efficient and intelligent alternatives. With BYD shifting focus to electric vehicles, the market for used fuel-powered cars has cooled, and the S6 lacks upgrade potential. Accelerated depreciation naturally makes its price more affordable, but one must weigh the risks of subsequent maintenance and comfort.
