车还回去几周之后，一封信来了：超额磨损、超里程、处置费，加起来上千。多数人的第一反应是「只能认了」。
但这张账单里有一项是可以完全验算的：超里程费 =（实际里程 − 合同允许里程）× 合同写的每英里费率。三个数都在你手上。这一项经常算错——用错费率、用错合同里程、或者忘了扣宽限额——而几乎没有人去核。代码替你算一遍，把差额直接摆出来。差额存在时，只需要一句话：「请说明这一项用的里程数和费率」。
其余的磨损收费按类别拆开（轮胎／玻璃／车身／内饰／缺件／各类费用），并指出哪几类通常有别的处理办法：缺的第二把钥匙自己买了寄过去往往比按账单价赔便宜；玻璃崩点很多地方可以低价修补；轮胎如果只是花纹不达标，自己换远比账单价划算——只是这些都要在还车之前做。
任何阈值数字这里都不给（凹陷多大算超额、花纹剩多少算不合格）：它们写在你那份租赁合同的「正常磨损标准」附件里，各品牌各年份不同，用错了反而削弱立场。
最有用的一步其实很简单：先要检查报告，不要先付款。检查报告应当包含每一项的照片、位置和测量值——拿不出逐项证据的收费，是最容易被撤销的。而异议要逐项写，不要笼统地说太贵。

A few weeks after you hand the car back, a letter arrives: excess wear, excess mileage, disposition fee — over a thousand. Most people assume it's fixed.
But one line on that bill can be checked exactly: excess mileage = (miles driven − contract allowance) × the per-mile rate in your lease. All three numbers are in your hands. This line is frequently wrong — wrong rate, wrong allowance, or a grace amount not deducted — and almost nobody checks it. The code recomputes it and shows the gap. Where there is one, a single sentence does the work: "please state the mileage figure and rate used for this charge".
The wear charges are grouped by type (tyres, glass, bodywork, interior, missing items, fees), with the categories that usually have a cheaper route: a missing second key is often cheaper to buy and post than to be billed for; a small windscreen chip is often repairable; tyres below tread spec cost far less replaced yourself — though all of those had to happen before the handover.
No threshold numbers are given here (how large a dent counts, how much tread is acceptable): they're in your lease's own wear standard, they differ by brand and year, and citing the wrong ones weakens your position.
The most useful step is simple: ask for the inspection report before paying anything. It should include a photograph, location and measurement for every charge — a charge with no item-level evidence is the easiest kind to have removed. And dispute line by line, never as a general complaint.
$3 unlocks an itemised dispute letter, what to check in the inspection report, and the escalation path when they won't move.
逐项异议信模板（每一类收费该怎么写、要求对方提供什么）、检查报告的核对清单（照片、时间戳、测量值、还车后损伤的界定）、缺件与轮胎玻璃的替代处理方式，以及对方不让步时的升级路径与信用记录的处理。An itemised dispute letter with what to demand for each charge type, a checklist for the inspection report (photographs, timestamps, measurements, post-handover damage), cheaper routes for missing items, tyres and glass, and the escalation path — including how to protect your credit record while disputing.
本工具不提供法律意见，也不判断任何一项收费是否合理。 超里程费的验算完全基于你填写的合同里程、实际里程与费率，这三个数必须以租赁合同与账单原件为准。「正常磨损」与「超额磨损」的具体标准（尺寸、深度、数量）写在你的租赁合同及其附件中，各品牌、各年份、各地区不同，本工具刻意不提供任何阈值数字。费用能否减免、异议如何提出、逾期是否影响信用记录，均取决于你的合同条款与所在地规定；争议金额较大或已进入催收时，请咨询律师或向当地消费者保护部门反映。请勿因本工具的输出而拖欠无争议部分——逾期可能产生额外费用并影响信用记录。你填写的内容不入库。
This is not legal advice and does not judge whether any charge is reasonable. The mileage recomputation relies entirely on the allowance, actual mileage and rate you enter; the lease and the bill itself govern those figures. What counts as normal versus excess wear (sizes, depths, counts) is defined in your lease and its wear schedule and differs by brand, year and region — no thresholds are given here, deliberately. Whether charges can be waived, how to dispute, and whether non-payment affects your credit depend on your contract and local rules; for significant amounts or once collections are involved, consult a lawyer or your consumer protection authority. Do not withhold undisputed amounts on the strength of this output — late payment can add fees and affect your credit record. Nothing you enter is stored.
