10 tips when renting a car

Picking up a hire car for the first time can feel more complicated than it needs to be, especially in a country you do not know well.

A few simple habits make the whole process faster, cheaper and considerably less stressful, whether you collect the car at Sofia Airport or in the city centre.

Below are ten practical tips built from years of handing over keys to holidaymakers, business travellers and returning customers, plus a short FAQ covering the questions we hear most often.

Why planning ahead makes car hire easier

Most problems renters run into come down to timing rather than the car itself. Booking at the last minute narrows your choice of vehicle and often pushes the price higher, especially during the busy summer months and around public holidays.

Working out your route and rough mileage before you arrive also helps you choose the right category of car from the start, rather than paying extra to switch vehicles halfway through the trip.

It is worth deciding early whether you need the car mainly for airport pickup, day trips around Sofia, or a longer route across the country, since each scenario suits a different type of car and rental length.

Ten tips for a smooth car rental experience in Bulgaria

The list below follows the full rental cycle, from the moment you book to the moment you hand back the keys, in the order most travellers experience it. Some tips take only a minute to apply, while others are simply a change in mindset, but each one removes a small source of friction from the trip.

1. Book your dates and route in advance

Reserve your car as soon as your travel dates are confirmed, particularly if you are travelling in July or August or around Christmas and Easter, when the most popular models sell out first.

Early booking also gives you time to compare classes and check current prices before you commit, rather than accepting whatever is left on the day.

If your plans are flexible, renting on a weekday rather than over the weekend can also bring the daily rate down.

One-way rentals, where you collect the car in one city and drop it off in another, usually carry a separate fee, so confirm this in advance if your itinerary needs it.

2. Choose a car that matches your trip and your budget

A larger or more powerful car is not always the better choice. For two people driving mainly around Sofia and nearby towns, a car from the economy class is usually enough and keeps both the rental price and fuel costs down.

Families or groups with more luggage should size up a class or two, since a cramped boot on a two week holiday causes more frustration than the small difference in price.

Think honestly about how you will actually use the car, city parking, mountain roads, motorway driving, before picking a category rather than choosing on looks alone.

3. Weigh up deposit and risk before choosing a higher class

Premium and 4x4 vehicles, such as those in our SUV range, typically carry a larger security deposit than a compact hatchback, since repair costs on a more expensive car are higher.

Decide in advance whether you are comfortable with a larger hold on your card for the length of the rental, since this amount is blocked rather than charged unless there is damage.

If a smaller deposit matters more to you than extra space or power, a standard or compact car is usually the more relaxed option for a first rental in a new country.

This is worth discussing with the rental desk before you sign anything.

4. Check your documents and driving licence in advance

Bulgarian rental companies need to see valid identification and a driving licence before handing over any car, so it helps to check exactly what is required before you travel rather than at the counter.

Before you travel, make sure you have the following documents and items ready:

• Passport or national identity card;
• A valid driving licence held for the minimum required period;
• An International Driving Permit, if the licence was not issued in an EU or EEA country;
• A credit or debit card in the name of the main driver, for the deposit.

Our dedicated guide on documents needed to rent a car in Bulgaria goes through each requirement in more detail, including the exceptions for EU licence holders.

5. Inspect the car thoroughly before you drive off

Once you collect the car, whether at Sofia Airport or from our office, walk around it slowly before signing anything.

Check the bodywork, alloys and windscreen for existing scratches or chips, look inside the boot, and confirm the fuel gauge reading matches what is written on the handover form.

Any marks noticed at this stage should be written into the rental form on the spot, since this is the record that protects you when the car is returned.

Doing this in daylight, rather than late at night, makes small marks far easier to spot.

6. Test the engine, lights and controls on the spot

Before leaving the car park, start the engine, check that the headlights, indicators and hazard lights all work, and adjust the mirrors and seat to a comfortable driving position.

If you plan to drive straight after a long flight, consider our transfer service instead for the first leg, and collect the car once you have rested.

A short test drive around the car park, rather than heading straight onto the motorway, is the safest way to get used to an unfamiliar gearbox and pedal feel.

This is also the moment to confirm the boot and doors lock properly with the key provided.

7. Drive carefully and know the local rules

Bulgarian law requires headlights on at all times outside built up areas, seat belts for every passenger, and hands free devices only for phone calls while driving.

Speed limits are generally 50 km/h in towns, 90 km/h on open roads and up to 140 km/h on motorways, and cameras are common on the main routes.

Our guide to driving in Bulgaria covers these rules in more depth, including parking, vignettes and what to do if you are stopped by traffic police.

Careful, defensive driving keeps both you and the deposit on your card fully intact.

It is also worth avoiding rural back roads after dark, since lighting and surface quality can vary widely away from the main towns.

8. Return the car in the condition you received it

Bring the car back with a clean interior and the same fuel level noted at collection, since fuel and cleaning are billed separately from the rental price itself.

Any traffic fines, tolls or vignette charges issued after you return the car remain the responsibility of the driver named on the agreement, not the rental company.

Arriving a little earlier than the deadline gives staff time to check the car calmly, rather than rushing the handover at the last minute.

If your plans change, let the team know at least two days beforehand rather than simply returning the car early or late.

This keeps the paperwork accurate for both sides and avoids any confusion once the deposit is checked and released.

9. Photograph any existing damage straight away

Beyond noting marks on the rental form, take a few photographs of the car with your phone before you drive away, covering each side, the roof and the number plate.

Time stamped photographs are useful evidence if there is ever a disagreement about a mark that was already there when you collected the car.

Our article on the guarantee fund explains how the security deposit works and what happens to it once the car is returned undamaged.

Keep these photographs safe until the deposit has been released back to your card.

A few extra minutes here can save considerable back and forth later.

10. Make sure you actually need a rental car

Before confirming anything, consider whether a taxi, a transfer, or public transport might actually suit your trip better than a self drive car.

For a single airport run or an evening event, a driver may be simpler than parking and navigating an unfamiliar city.

If a self drive car is genuinely what you need, booking a rental car online in Bulgaria takes only a few minutes, and the SpeedyCars team is available by phone to help with any last questions before you travel.

Weighing this up honestly before you book saves both money and hassle later in the trip.
