After the search, pick the gearbox and car size from the buttons above the results to match the car you already booked — otherwise we'll compare against something you may not want.

Who did you book with? optional

It doesn't change your results — it tells us which sites people are leaving, which is how we decide what to build next.

Trip costs Driving far? Add the distance and we cost the energy — and flag any car whose included mileage you'd exceed

Trip distance (km) 0 = no fuel estimate

Petrol/diesel, per litre

Charging, per kWh

An assumption, not a quote: we apply a typical consumption for the car's size and fuel (electric cars are costed in kWh, not litres) and show the figure used on each card. Rentals are "or similar", so the exact car is unknown until the desk. Included-mileage caps are shown too — going over is charged by the supplier at a rate they set, which we cannot see, so it is never in these totals.

One lookup per date-slot, politely paced — a 90-day chain takes about a minute.

Cover the excess for less

Take the cover at checkout, not at the desk

DiscoverCars’ Full Coverage is €81.55 for this rental (€11.65/day). Over 7 days that is the cheapest way we can find to cover the excess, and far below the €15–25 a day the rental desk charges for the same protection. Tick Full Coverage on DiscoverCars when you book. Whatever you choose, the deposit is still held on the main driver’s card at pick-up.

We may earn a share of Full Coverage bought through DiscoverCars, at no extra cost to you. General information, not insurance advice - compare cover before you buy.
