How to avoid hire-car scams

By the Viamo editorial team · Editor Terje Moy · Last updated July 2026 · 7 min read

Most car-hire transactions are entirely straightforward, but a small number of desks — often at busy leisure airports, sometimes independent operators rather than the big international brands — rely on a handful of well-worn tactics to squeeze extra money out of travellers who don't know what to look for. None of it is complicated to avoid once you know the pattern. Here are the scams that come up again and again, and the specific habits that shut each one down.

The pre-existing damage claim

This is the single most common complaint from hire-car customers, and it isn't always a deliberate scam — sometimes it's genuine sloppiness at the inspection stage — but the outcome is the same either way: you're charged for damage you didn't cause, discovered (or claimed) after you've already left. It typically surfaces days or weeks after you've returned home, as a charge to the card you booked with, often for a scratch, a scuffed alloy or a small dent that "wasn't on the original inspection form."

Get every mark noted on the paper or digital inspection form too, not just photographed — some companies only accept disputes referencing the form itself. If a company hurries you through the walk-around or discourages you from photographing the car, treat that as a signal to slow down and do it properly anyway; a legitimate company has no reason to mind. Our step-by-step guide to renting a car abroad for the first time covers this inspection process in more detail if you haven't hired before.

The fuel policy switch

Full-to-full — you collect with a full tank and return with a full tank — is the fairest and usually cheapest policy for the customer. A common desk tactic is to push a prepaid fuel option instead, framed as convenient ("just bring it back on empty, no fuss"), when in reality prepaid fuel is priced to assume you won't use the whole tank, meaning you pay for fuel you never burn. Some desks go further and simply charge the prepaid option by default unless you actively decline it, hoping you won't notice on a long, tiring form.

Read the fuel line on the contract before you sign, not after. If it says anything other than the policy you agreed to when booking, query it at the desk — reversing a fuel charge after the fact, once you've left the country, is far harder than catching it in the two minutes it takes to read the paperwork properly.

The relentless insurance upsell

The excess waiver, "super cover" or similarly branded add-on is a legitimate product, but it's also sold at a significant premium at the desk compared with buying equivalent cover in advance — and some desk staff are trained to keep pushing after a polite "no thank you," implying the standard cover included in your booking is riskier than it actually is, or exaggerating what an accident would cost you without the upgrade. See our guide to car hire insurance explained for what each layer of cover actually does and how to price it properly before you travel, so you're not weighing up an unfamiliar insurance product for the first time with a queue building behind you.

• Decide before you arrive whether you want the desk's excess waiver, a standalone policy, or credit-card cover — and stick to that decision at the counter.
• A firm, single "no, thank you" is enough. You are not obliged to explain your reasoning or justify your existing cover.
• If the desk claims your online booking's included insurance "doesn't really cover anything" or is being deliberately vague about what it excludes, ask for that in writing — vague scare tactics rarely survive a direct written request.

The category or car swap

You book a specific category online, and at the desk you're told that category isn't available — with an "upgrade" offered at extra cost, positioned as the only real alternative. Sometimes this is a genuine, unavoidable shortage; sometimes it's a way to extract a higher margin by steering bookings towards a category the branch prefers to move that day. Either way, a genuine unavailability should come with a fair alternative at no extra cost, not a paid upgrade as the default first offer. This tactic is a distant cousin of the fee games that turn up around one-way hire and drop-off charges, where a headline price can look far better than the total once every extra is added.

If you're offered a costed upgrade for an unavailability that isn't your fault, ask specifically whether a same-price alternative exists first. If none does, and the company's own terms guarantee your booked category or a fee-free upgrade (many do, in the small print), point to that clause rather than accepting the upsell as the only option.

Card skimming and the deposit hold

The large deposit hold placed on your credit card at pick-up is standard practice everywhere, not a scam in itself — but it's worth checking the amount debited matches what you were told verbally, and confirming it's a hold rather than an immediate charge (your bank's app or a call to your card issuer will usually show the difference). Genuinely fraudulent card skimming at rental counters is rare compared with the disputes above, but using a card with fraud alerts switched on, and checking your statement in the weeks after the trip, costs nothing and catches most problems early.

Unlicensed or "meet and greet" operators outside the airport

At some destinations, particularly busy leisure airports, touts or unofficial operators approach arriving passengers in the terminal offering cheap car hire away from the official desks. These arrangements typically have no real recourse if something goes wrong — no genuine insurance backing, no complaints process, and often a vehicle that isn't properly registered for rental use at all, and often no proper proof of valid motor insurance either if you end up driving it across a border. Book through a recognised international brand or a reputable comparison platform in advance, and walk past anyone approaching you in the arrivals hall with an unsolicited car-hire offer, however good the price sounds.

What to do if you think you've been scammed

1. Gather your evidence immediately — the inspection form, your photos and video, the original booking confirmation and the rental contract.
2. Dispute the charge directly with the rental company in writing first, referencing the specific evidence.
3. If that fails, dispute the charge with your card issuer — most offer a formal chargeback process for exactly this kind of dispute, and your photographic evidence is what makes a chargeback succeed.
4. For rentals booked within the EU, consumer protection rules give you further routes if the company is unresponsive — the European Commission publishes guidance on this.

Frequently asked questions

How do I prove I didn't cause damage the company is charging me for?

Timestamped photos and video taken at both pick-up and drop-off are the strongest evidence. Combine them with the signed inspection form noting any pre-existing marks, and raise the dispute in writing as soon as the charge appears.

Is it normal for a rental desk to push insurance hard even after I've said no?

A single offer is normal; repeated pressure after a clear decline is a common upsell tactic rather than standard practice. Decide your cover in advance and give one firm answer rather than getting drawn into a back-and-forth at the counter.

Is it worth booking through a comparison site rather than directly?

Both can work well, but stick to recognised platforms and international brands rather than unlicensed operators offering deals outside the terminal. Read the small print on cancellation and what's included before comparing headline prices.

Can I get my money back if I already paid for an unnecessary upsell?

Sometimes, particularly if you can show it was added without clear consent or misrepresented at the desk. Raise it directly with the company first, then escalate to your card issuer's dispute process if that doesn't resolve it.
