Planning a Trip? 5 Things That Often Stay Hidden When Renting a Car

September 18, 2026 · 6 min read

When you're planning a vacation, a business trip, or just a few days out of town, renting a car should be one of the easiest parts of the whole trip. You pick a car, you book it, you grab the keys and go.

In practice, it's not always that simple. Renting a car comes with a few details that can change both the price and your entire experience — from which car you actually get, through insurance and mileage limits, to how much time you'll spend filling out paperwork.

So before you book a rental car, it's worth knowing exactly what you're getting for the price you see.

At Auto Aleya, we believe a customer shouldn't find out the important terms only when they arrive at the counter. That's why, drawing on more than 20 years of experience, we work by one simple principle: clear terms, a real car, and no unpleasant surprises at return.

Here are 5 things worth paying attention to.

1. Do you get the car you actually booked?

One of the most common rental-car surprises is the well-known phrase: "or similar vehicle." You see a specific model in the photo, you choose it, you plan your trip around it — and at pickup you find out the car can be swapped for a different one from the same class.

In theory, that might be normal practice. For the customer, though, "similar" doesn't always mean the same. Size, trunk space, engine, equipment, fuel consumption, and how the car actually feels to drive can all be different.

How to protect yourself? Before booking, check whether the specific model is guaranteed, or whether the company reserves the right to swap it for another vehicle.

How do we do it at Auto Aleya? Our philosophy is simple: what you see is what you drive. When you choose a specific vehicle from our fleet, the idea isn't to hand you "or similar" — it's to give you exactly the car you chose. That matters especially when you have specific needs — more trunk space, a child seat, an automatic gearbox, or a particular type of car.

2. What does the insurance on a rental car actually cover?

The price you see when searching for a rental car doesn't always tell the whole story. It's important to know what it includes — and, above all, what your liability is in case of damage or an accident.

Before booking, check:

  • is there collision damage waiver (CDW);
  • is there third-party liability cover;
  • is there theft protection;
  • what the excess (deductible) is;
  • are there additional restrictions;
  • how are damages to tires, windows and other parts handled;
  • what additional options are available to reduce your liability.

These are details that can seem unimportant — right up until something happens. When there's damage, they're often the most important part of the contract.

How do we do it at Auto Aleya? Our car prices include the necessary insurance coverage under the specific rental terms, and any additional protection options are described upfront. We also offer Full CDW for customers who want to further reduce their liability under the applicable terms.

Our principle is simple: the terms should be clear before the booking, not at drop-off. To learn more about coverage and terms, see our page on rental car insurance.

3. Is there a mileage limit?

Imagine picking up a car in Sofia, planning to drive to the coast, visit a few places, and then come back. The last thing you want is to spend the whole trip worrying about going over your allowed mileage.

Some rental offers come with a daily or total mileage cap. Going over it can mean an extra charge. So always check: how many kilometers are included in the price?

How do we do it at Auto Aleya? Our short- and medium-term rentals come with unlimited mileage, under the specific terms of the offer. That means you don't need to plan your route around a kilometer count.

Running errands in Sofia? Heading to the coast? Planning a road trip around Bulgaria? Drive based on what you actually need — without counting kilometers.

4. How old is the car you'll actually get?

When you rent a car, you're not just renting transport from point A to point B. The car is part of the trip itself. Its condition matters — especially over hundreds of kilometers.

An older car with high mileage can be perfectly roadworthy, but the feel, comfort, and technology can be very different from those of a new car.

So when comparing rental cars, don't look at the daily price alone. Also look at:

  • the year the car was made;
  • its condition;
  • its equipment;
  • how well it's maintained;
  • the actual car you'll get.

How do we do it at Auto Aleya? Our fleet is built from current Volkswagen and Audi models, with cars under 2 years old. We maintain them regularly and pay attention not only to technical condition, but also to the cleanliness and state in which a car is handed to the next customer.

For us, a new car isn't just a marketing advantage. It's part of our promise to the customer: a clean, well-maintained, modern car you can confidently continue your trip in.

5. How long does picking up the car actually take?

After a long flight or a busy work day, no one dreams of a long wait, a stack of forms, or unclear procedures. That's why, when choosing a car rental in Sofia, it's worth paying attention not just to the car and the price, but to the process itself.

How does the booking work? What documents are required? How much information do you need to fill in? How is pickup and return organized?

How do we do it at Auto Aleya? We aim to make the process as clear and convenient as possible, well before you arrive. You can book online, get information about the car and the terms in advance, and arrange pickup ahead of time.

If you need a car at Sofia Airport, we organize pickup according to the service you choose and the agreed terms. If you're arriving by plane, read more about renting a car at Sofia Airport.

How to choose a rental car without unpleasant surprises

Before you hit "Book," take a few minutes to check five things:

  1. What car will you actually get?
  2. What does the insurance cover, and what's your liability?
  3. Is there a mileage limit?
  4. How old is the car?
  5. How does pickup and return work?

These questions might seem small, but they're often what separates a cheap-looking deal from a well-organized car rental.

At Auto Aleya, we believe good service doesn't start when we hand over the keys. It starts the moment a customer looks at the car and the terms online. That's why our principle has stayed the same for years: what you see is what you drive. What's written is what you get. No hidden terms, no unpleasant surprises.

And when everything is clear upfront, all that's left is the best part: get in, start the engine, and go.
