报价单当场看不懂，是因为它把三类完全不同的东西混在一起：这次必须修的、可以等到下次的、顺带推销的。而你正站在车间里，时间被挤压，对方在等一个「行」。
把项目一行一行敲进来，代码按名称归到五类——安全相关、渗漏异常、常规保养、增值清洗类、工时费用——并算出每一类占总额的比例。「增值清洗类占了 41%」这个数字比任何「你是不是被宰了」的判断都有用，因为它可以当场拿给对方看。
价格本身这里不给参考值。 地区、车型、配件品牌（原厂／品牌件／副厂）差别太大，给一个「正常价」反而会误导你去争一个错的点。工具给的是该问哪几行、以及怎么问。
对安全相关项，三个问题就能问清楚：现在是什么状态（要数字不要形容词）、能不能给我看一下、还能开多久。不愿意让你看是最明确的信号。
对增值项，一句话就够：「这几项这次先不做，我们只做和今天这个问题相关的。」不需要理由。如果对方坚持，再问「不做会有什么后果？多久之内必须做？」——能说出具体后果和时间的通常是真的，说不出来的通常就是这一类。

A repair quote is unreadable on the spot because it mixes three different things: what must be done today, what can wait, and what's being sold to you. Meanwhile you're standing in the workshop, time is short, and someone is waiting for a yes.
Type the line items in and the code sorts them by name into five groups — safety, leaks and faults, scheduled maintenance, add-on cleaning services, labour and fees — and computes each group's share of the total. "Add-ons are 41% of this quote" is far more useful than any verdict about being ripped off, because you can show it to them right there.
No reference prices are given here. Region, model and parts tier (OEM, branded aftermarket, generic) vary too much, and a "normal price" would send you arguing about the wrong thing. What you get is which lines to question, and how.
For safety items, three questions settle it: what's the current measurement (a number, not an adjective), can you show me, and how much longer can it run. Refusing to show you is the clearest signal there is.
For add-ons, one sentence: "we'll skip these today and only do what relates to why I came in." No justification needed. If they push, ask what happens if you don't and by when it must be done — a specific consequence and timeframe usually means it's real; the absence of one usually means it isn't.
$2 unlocks per-item questions and what the answers mean, how to ask about parts tiers and their price differences, and a comparison sheet to take to a second shop.
逐项的追问清单（每一项该问什么、什么样的回答说明是真的）、配件档次（原厂／品牌件／副厂）与价格差的问法、二次比价用的对照单模板、以及事后发现多收了该怎么处理。Per-item questions with what a credible answer sounds like, how to ask about parts tiers and their price gaps, a comparison sheet for a second opinion, and what to do if you find you were overcharged afterwards.
本工具不提供任何汽车维修或安全建议，也不判断某一项该不该修。 分类按项目名称的关键词匹配，是粗口径参考，会归错也会漏；占比只是算术，不代表任何一项是否合理或价格是否公道。本工具刻意不提供价格参考值——地区、车型、配件品牌与工时标准差异极大。涉及刹车、轮胎、转向、悬挂等安全部件时，请以有资质的技师现场检查为准，不要因为本工具的分类而推迟安全相关的维修。如对报价有争议，可要求书面报价单与旧件返还，并向经营者所在地的市场监管部门或消费者协会反映。你填写的内容不入库。
This provides no automotive or safety advice and does not judge whether any item should be done. Categorisation is keyword-based on item names — rough, and it both mis-sorts and misses. The percentages are arithmetic only and say nothing about whether an item is justified or fairly priced. No reference prices are given, deliberately — region, model, parts brand and labour rates vary enormously. For brakes, tyres, steering and suspension, rely on a qualified technician's physical inspection, and do not defer safety work because of how this tool grouped a line. If you dispute a quote, request it in writing and ask for the replaced parts back; disputes can be raised with your local consumer protection authority. Nothing you enter is stored.
