Two car hire quotes at the same airport for the same class of car, both showing €131 for a week. One has a €1,200 deposit, a full-to-empty fuel policy and 1,000km included. The other has a €300 deposit, full-to-full fuel and unlimited mileage. These are not the same product and they do not cost the same amount.
Discover Cars' distinguishing feature is that it tells you which is which on the results page, before you have invested any effort in choosing.
Disclosure as a feature
On the results list, each option shows the deposit amount, the fuel policy, the mileage allowance and the supplier's rating. That information exists on every broker's site; on most of them you find it after clicking through two screens, by which point you have anchored on a price.
The effect is that comparison actually works. You can see that the cheap option requires a €1,200 hold on your card and returns empty, and you can decide that the €12 more expensive one with full-to-full and a €300 deposit is the better buy. That decision is much harder to make on a site that leads with a single number.
This is a modest-sounding advantage. In a category where the gap between the advertised price and the amount that leaves your account is the central consumer problem, it is the most valuable thing a broker can do.
The coverage product
Like every broker, Discover Cars sells its own damage cover — marketed as full coverage — at a daily rate well below what the rental desk charges for its excess waiver.
The same critical caveat applies as with Rentalcars.com, and it bears repeating because it is where people get caught: this is reimbursement cover, not a reduced excess. The rental company will still hold your deposit and still charge you for damage. You claim it back afterwards.
That is a legitimate product and usually good value. It requires you to have the credit limit for the deposit and the patience for a claim. If you want the desk to simply not charge you, you have to buy the desk's own product at the desk's own price.
Discover Cars' documentation of what its coverage includes — and excludes: typically tyres, glass, undercarriage and roof vary by policy — is clearer than most. Read the exclusions before assuming you are covered for the gravel road you are planning to drive.
Cancellation
Free cancellation up to 48 hours before pickup applies to most bookings, which is a genuinely useful default and better than several competitors. Car hire is often booked months in advance and plans move; being able to rebook when the price drops, without penalty, is worth real money.
Supplier variance, again
This is unavoidable in broking. The cheapest supplier at any given airport is usually a local operator with an off-site lot, and the experience ranges from efficient to an hour on a shuttle bus followed by a hard sell.
Discover Cars puts supplier ratings front and centre, which is the right response. Use them. The difference between a 7.2-rated supplier and an 8.8-rated one is typically £20 on a week's rental and a completely different morning.
Practical method
Search, then sort mentally by total cost rather than headline price: deposit, fuel policy and mileage all convert into money.
Filter out suppliers below about 7.5 unless the saving is very large.
Buy the broker's coverage if you are comfortable with a deposit hold, and read the exclusions.
Photograph the car comprehensively before leaving.
Compare the final total against the rental company's own site — sometimes direct wins.
The exclusions that catch people
Broker coverage is cheap because it excludes things the desk's own waiver covers. The list varies by policy and market, and it typically includes some combination of:
Tyres, wheels and hubcaps — the most common damage on hire cars and the most common exclusion.
Glass, including windscreen chips.
Undercarriage and roof, which matters on rural or unpaved roads.
Interior damage, including smoking and upholstery.
Lost keys, which can run to several hundred euros with a modern immobiliser.
Wrong fuel, a surprisingly frequent and expensive mistake.
Read the specific policy wording before you assume you are covered for the gravel track to the villa. If your trip involves unpaved roads, the desk's own product — expensive as it is — may genuinely be the better buy.
Booking early, then rebooking
The free cancellation up to 48 hours before pickup enables a strategy that saves real money and almost nobody uses.
Car hire prices move a great deal, and they usually rise as availability tightens. Book early to secure a price, then re-check the same search every few weeks. If the price falls, book the cheaper option and cancel the original at no cost.
On a two-week summer rental in a peak market, we have seen this swing by more than a hundred euros in both directions. Ten minutes of attention, spread over a few weeks, is the best-value work available in this category.
Verdict
7.1. Discover Cars is the same fundamental business as Rentalcars.com executed with better disclosure, and disclosure is precisely what this category lacks. Putting the deposit, the fuel policy and the mileage limit next to the price turns a misleading comparison into a real one.
It does not escape the structural issues of broking — two contracts, reimbursement cover, variable local suppliers — which is why it sits in the middle of our scale rather than higher. But if you are going to use a broker, use this one.
