How to Inspect a Used Car Before You Buy It from China

You are buying a car you cannot touch, in a country you are not in. That is normal in this trade — and it is manageable, provided you ask for the right evidence in the right order. Here is the checklist we work through with overseas buyers.

Why remote inspection is a different discipline

Inspecting a used car in person is mostly sensory: you hear the cold start, feel the gearbox, smell the cabin. Buying from China removes all of that. What replaces it is documented evidence you control — a specific photo set, a specific report, and a live video where you, not the seller, decide where the camera points.

The failure mode is not "the car was bad". It is "the buyer paid before the evidence existed". Almost every dispute we are asked to help with starts the same way: a deposit sent on the strength of three flattering photographs.

Step 1 — documents before photographs

Photographs tell you what a car looks like. Documents tell you what it is. Ask for these first:

  • Vehicle registration and VIN — the 17-character chassis number must match across the windscreen plate, the door-jamb plate and the paperwork. A mismatch ends the conversation.
  • Maintenance and service history — dealer records show mileage at each visit; that is your odometer cross-check.
  • Insurance claim history — in China this is queryable through vehicle-history data providers and reveals accident payouts the seller may not volunteer.
  • Independent inspection report — not the seller's own word, but a structured report from a recognised inspection provider.

Step 2 — the twelve photographs to demand

Ask for this exact set. A seller who can produce all twelve quickly is usually a seller with nothing to hide; evasion here is itself information.

#PhotographWhat it reveals
1–2Front and rear three-quarter views, in daylightPanel gaps, colour mismatch between panels, stance
3All four door-jamb platesVIN consistency, build date, factory specification
4Windscreen VIN, shot from outsideConfirms the shell has not been swapped
5Odometer with the engine runningMileage, plus warning lights that stay lit
6Engine bay from directly aboveOriginal welds, sealant beads, crash repairs
7Both front strut towersThe classic tell of front-end impact repair
8Underbody, front to rearRail damage, fresh underseal, impact deformation
9All four tyre DOT codesTyre age and whether they were replaced as a set
10Spare-wheel well, liner removedSilt, rust and water staining — the flood tell
11Seat rails and under-dash wiringRust on unfinished metal; corroded connector pins
12Paint-thickness gauge on every panelFiller and repainting, numerically instead of by eye

Step 3 — structural red flags

Cosmetic damage is negotiable; structural damage is not. Three categories matter:

Accident repair

Factory seam sealant is applied in an even, machine-like bead. Repaired areas show hand-applied, uneven sealant. Original spot welds are uniform dimples; repair welds are ground flat or irregularly spaced. A paint gauge reading above roughly 200 microns on a steel panel usually means filler; readings that differ wildly between adjacent panels mean a partial respray.

Flood damage

Flooded cars are almost always detailed before sale, which is why the cabin smells of perfume rather than water. Look instead at unfinished metal: seat rails, spring coils, the spare-wheel well, and connector pins under the dashboard. Rust or silt in those places cannot be valeted away.

Fire damage

Check the firewall and wiring loom for melted insulation or replaced sections, and look for heat discolouration on surrounding metal. Fire-damaged vehicles are rare but should be rejected outright.

Step 4 — mechanical and electronic checks

  • Cold start — insist the video begin before the engine is started. Blue smoke on start-up indicates valve-stem or turbo wear.
  • Idle quality — a steady idle after warm-up; hunting or vibration points to mounts, injectors or ignition.
  • Transmission — on the video, ask for a slow forward-and-reverse shuttle. Delayed engagement or a flare between gears is expensive.
  • OBD diagnostic read — request the report's fault-code section. Beware a "clean" scan taken immediately after codes were cleared; a drive cycle re-populates pending faults.
  • Wear-versus-mileage consistency — pedals, steering wheel rim, driver's seat bolster and brake discs should agree with the odometer.

Step 5 — what changes for EVs and plug-in hybrids

A combustion car's expensive failures are mechanical and audible. An EV's expensive failure is silent and chemical. For any battery-electric or plug-in model, add:

  • State of health (SOH) from a diagnostic read-out, not a dashboard estimate. Below roughly 85% on a car that is only a few years old deserves an explanation.
  • Charge-cycle count and whether the car was used in commercial or ride-hailing service.
  • Real-world range test — a full charge to a stated percentage against distance travelled, not a guess.
  • Pack casing inspection — scrapes, deformation or swelling underneath.
  • Warranty transferability — whether the manufacturer's battery warranty follows the vehicle to an overseas owner.
  • Charging standard — GB/T is the Chinese standard; confirm compatibility or the adapter plan for your market.

What a structured inspection actually covers

To make this concrete: our own intake inspection is a 158-point checklist spanning exterior, structure, engine, transmission, chassis, electronics, OBD diagnostics, odometer authenticity, interior and tyres. It is backed by independent inspection data from ChaBoshi (查博士), a Chinese used-car data and inspection provider, and delivered as a bilingual Chinese/English PDF. Vehicles with accident, flood or fire history are rejected at intake rather than discounted.

We also send a live WhatsApp walk-around within 24 hours of an inquiry, and we welcome a third-party inspector you commission yourself to attend our Beijing facility. If a seller resists any of those three, treat that resistance as the finding.

Red flags that should end the deal

  • Payment requested to a personal bank account rather than the company's.
  • Refusal of a live video, or a video that never lingers where you ask.
  • No export licence, or reluctance to show the deregistration certificate.
  • A price far below comparable stock, explained away as "cash deal".
  • An inspection report that is a brochure rather than a document with measurements.

Frequently asked questions

Can I inspect a used car from China without flying there?

Yes. Three layers replace a physical visit: a written inspection report with photographs, a live WhatsApp walk-around video where you direct the camera, and an independent third-party inspection you commission yourself at the seller's facility. Serious exporters welcome all three.

Which photos should I demand before paying a deposit?

At least twelve: front and rear three-quarter views, all four door-jamb VIN plates, the windscreen VIN, the odometer with the engine running, the engine bay from above, both front strut towers, the underbody, all four tyre DOT codes, the spare-wheel well, the seat rails from underneath, and a paint-thickness gauge reading on each panel.

How do I tell flood damage from a photograph?

Look for rust or silt on seat rails and spring coils, mud staining inside the spare-wheel well, corroded connector pins under the dashboard, and musty or over-perfumed interiors. Flooded cars are usually detailed hard before sale, so under-dash wiring and seat-rail metal are the honest places to look.

What should I check on a used EV from China?

State of health (SOH) of the battery pack from a diagnostic read-out, charge-cycle count, a real-world range test rather than the dashboard estimate, physical damage or swelling on the pack casing, whether the manufacturer's battery warranty transfers to an overseas owner, and charging-port compatibility with your market.

How can I be sure the mileage is genuine?

Cross-check the odometer against three independent sources: the maintenance and service history, the inspection report's wear assessment (pedals, steering wheel, driver's seat bolster, brake discs), and a Chinese vehicle-history data query. A car showing 40,000 km with a worn steering wheel and new brake discs does not add up.

从中国买二手车前,如何验车

你买的这辆车,摸不到、也不在你所在的国家。这在这行是常态——只要按正确顺序拿到正确的证据,风险完全可控。以下是我们与海外买家逐项核对的清单。

为什么远程验车是另一套功夫

当面验车靠的是感官:冷启动的声音、变速箱的手感、车里的气味。从中国买车,这些全都没有了。替代它的是由你掌控的书面证据——一套明确的照片、一份明确的检测报告,以及一段由你(而不是卖家)决定镜头走向的实时视频。

真正会出问题的地方不是"车不好",而是"证据还没到手,钱先付了"。我们被请去协助处理的纠纷,几乎都始于同一个动作:凭三张好看的照片就打了定金。

第一步:先看文件,再看照片

照片告诉你车"长什么样",文件告诉你车"是什么"。先要这四样:

  • 车辆登记与车架号——17 位 VIN 必须在前挡风玻璃铭牌、门框铭牌与证件上完全一致。对不上就不用再谈。
  • 保养维修记录——4S 店记录会写明每次进厂的里程,这是核对里程表的依据。
  • 出险理赔记录——在国内可通过车辆历史数据平台查询,能查出卖家可能不会主动说明的事故赔付。
  • 第三方检测报告——不是卖家口头描述,而是正规检测机构出具的结构化报告。

第二步:必须索要的十二张照片

就按这个清单要。能迅速给全十二张的卖家,通常没什么好藏的;在这里含糊其辞,本身就是一条信息。

#照片能看出什么
1–2前、后 45 度全景(自然光下)钣金缝隙、相邻板件色差、车身姿态
3四个门框铭牌VIN 一致性、出厂日期、原厂配置
4前挡风玻璃处 VIN(车外拍摄)确认车身壳体未被更换
5发动机运转状态下的里程表真实里程,以及常亮的故障灯
6发动机舱正上方俯拍原厂焊点、密封胶条、事故修复痕迹
7左右前减震器塔顶车头撞击修复最典型的破绽
8底盘由前至后纵梁损伤、新喷底盘装甲、碰撞变形
9四条轮胎的 DOT 码轮胎年份,以及是否整套更换
10掀开衬板的备胎坑泥沙、锈蚀、水渍——泡水的破绽
11座椅滑轨与仪表台下方线束未喷漆金属件是否生锈;插头针脚是否腐蚀
12每块钣金的漆膜仪读数用数字而不是肉眼判断腻子与重新喷漆

第三步:结构性红线

外观损伤可以谈价,结构损伤不能。要分三类看:

事故修复

原厂密封胶是机器打的,均匀规整;修复部位的手工胶条参差不齐。原厂点焊是均匀的凹点,修复焊点被磨平或间距不整。钢制钣金漆膜读数超过约 200 微米,通常意味着刮了腻子;相邻板件读数差异过大,说明是局部补漆。

泡水

泡水车在出售前几乎都会被精洗,所以车里闻到的往往是香水味而不是霉味。要看没喷漆的金属件:座椅滑轨、弹簧、备胎坑,以及仪表台下方的插头针脚。这些位置的锈和泥沙,是洗不掉的。

火烧

检查防火墙与主线束是否有熔化、更换段落,以及周边金属的热变色痕迹。火烧车很少见,但一旦确认应直接放弃。

第四步:机械与电子检查

  • 冷启动——要求视频在启动前就开始录。启动冒蓝烟,说明气门油封或涡轮磨损。
  • 怠速品质——热车后怠速应平稳;抖动或游车,多半是机脚、喷油或点火问题。
  • 变速箱——视频里请对方缓慢前进—倒车来回切换。入挡延迟或换挡打滑,修起来很贵。
  • OBD 诊断读数——要报告里的故障码段落。注意"清完码立刻扫描"的干净结果;跑一个循环后,待定故障会重新出现。
  • 磨损与里程是否相符——踏板、方向盘圈、主驾座椅侧翼、刹车盘的磨损程度,应与里程表口径一致。

第五步:纯电与插混要额外看什么

燃油车贵重的故障是机械的、听得见的;电动车的贵重故障是安静的、化学的。任何纯电或插混车型,都要再加这几项:

  • 电池健康度(SOH)——以诊断仪读数为准,不是仪表盘估算。车龄只有几年却低于约 85%,需要对方给出解释。
  • 充放电循环次数,以及车辆是否用于营运或网约车。
  • 实际续航实测——满充到某一百分比对应的实际行驶里程,而不是拍脑袋的估计。
  • 电池包壳体检查——底部刮擦、变形或鼓包。
  • 质保是否随车转移——厂家电池质保能否延续到海外车主名下。
  • 充电标准——国内为 GB/T 标准;需确认与目标市场的兼容性或转接方案。

一份结构化检测到底覆盖什么

说具体些:我们的入库检测是 158 项清单,覆盖外观、结构、发动机、变速箱、底盘、电器、OBD 诊断、里程真实性、内饰与轮胎;并以国内车辆数据与检测服务机构查博士的独立检测数据作背书,出具中英双语 PDF 报告。有事故、水泡、火烧记录的车辆在入库环节直接拒收,而不是打折出售。

收到询盘后 24 小时内,我们还会发一段 WhatsApp 实车环视视频;也欢迎买方自行委托第三方检测机构到北京场地复检。如果卖家对这三件事中任何一件推脱,那么这个"推脱"本身就是检测结论。

应当直接终止交易的信号

  • 要求把款打到个人账户,而不是公司账户。
  • 拒绝实时视频,或镜头从不按你的要求停留。
  • 拿不出出口许可证,或不愿出示注销证明。
  • 价格明显低于同款行情,用"现金交易"来搪塞。
  • 检测报告像宣传册,而不是带实测数据的文件。

常见问题

不去中国,能验车吗?

能。三层证据可以替代到场:带照片的书面检测报告、由你指挥镜头的 WhatsApp 实时环视视频,以及你自己委托的第三方机构到卖家场地复检。正规的出口商对这三项都欢迎。

付定金前应该要哪些照片?

至少十二张:前、后 45 度全景,四个门框铭牌,前挡玻璃 VIN,发动机运转时的里程表,发动机舱俯拍,左右前塔顶,底盘,四条轮胎 DOT 码,备胎坑,座椅滑轨底部,以及每块钣金的漆膜仪读数。

怎么从照片判断泡水?

看座椅滑轨与弹簧是否生锈或有泥沙、备胎坑内是否有泥渍、仪表台下方插头针脚是否腐蚀、车内气味是否发霉或用香水掩盖。泡水车出售前通常都会精洗,所以仪表台下方线束和座椅滑轨金属是最诚实的两个位置。

从中国买二手电动车要看什么?

诊断仪读出的电池健康度 SOH、充放电循环次数、实际续航实测(而非仪表估算)、电池包壳体是否受损或鼓包、厂家电池质保能否转移给海外车主,以及充电接口与目标市场的兼容性。

怎么确认里程是真实的?

用三个独立来源交叉核对里程表:保养维修记录、检测报告里的磨损评估(踏板、方向盘、主驾座椅侧翼、刹车盘),以及国内车辆历史数据查询。一辆显示 4 万公里、却配着磨损的方向盘和新刹车盘的车,是不成立的。

想让某台车按这份清单过一遍?

把车源编号或你正在考虑的车型发给我们。我们会先给出检测报告、上述整套照片和实车环视视频——在任何人请你付款之前。
