How to get a specific rental car model—or the closest useful match.
Most rental offers reserve a class, not the example car pictured. Start by looking for an explicitly guaranteed model. If that is unavailable, choose a substitute that preserves the size, layout, powertrain, or routine you actually need to test.

Start with this usefulness ladder
| Rental match | How useful is it? | What it can tell you |
|---|---|---|
| Exact model, similar trim | Excellent | Strong test of size, seating, cargo, visibility, controls, parking, and general daily livability. Verify trim-specific differences separately. |
| Same model, different trim | Very useful | Usually strong for basic packaging and routine fit. Wheels, seats, suspension, powertrain, and equipment may still change the experience. |
| Close competitor or closely related vehicle | Useful for selected questions | Can test whether this general size and layout work for your life. Do not treat it as a review of the car you plan to buy. |
| Same rental category only | Limited but sometimes useful | Useful for broad size, cargo, parking, or family-fit questions. Weak for model-specific controls, ride, visibility, and driving feel. |
| Different body style or purpose | Usually poor | If the substitute changes the thing you wanted to test, it is the wrong proxy. A cargo van is not a pickup test. A three-row SUV is not a minivan sliding-door test. |
What “or similar” means on a car-rental offer
Direct answer: “Or similar” normally means you are reserving a vehicle class, not the example make and model shown in the result. Discover Cars states that a booking guarantees a class unless the offer specifically names the model and marks it as guaranteed by the rental company.
| Offer language | What to assume | How useful it is for this method |
|---|---|---|
| Example model + “or similar” | The pictured model is one possible vehicle in the class. | Judge the class and possible substitutes against the question you need to test. |
| Specific model marked guaranteed | The offer explicitly promises that model, subject to the booking terms. | Best option when model-specific controls, packaging, charging, or driving feel matter. |
The booking page is therefore the start of the matching process, not the end. Check the category, body style, seating, fuel type, transmission, and other listed specifications. Then decide whether the possible vehicles could still answer your test questions.
Match the rental to the question you want answered
| If you are shopping for… | Start your search around… | Do not compromise on… |
|---|---|---|
| Compact crossover | Compact or intermediate SUV/crossover categories | Body style and approximate exterior size if garage and parking fit matter. |
| Two-row midsize SUV | Intermediate or standard SUV categories | Two-row layout and approximate size if cargo and maneuverability are the test. |
| Three-row SUV | Three-row SUV or larger SUV categories where seating is clearly shown | An actual third row. A two-row substitute cannot answer third-row questions. |
| Minivan | Minivan category | Sliding doors and minivan seating layout. An SUV is not an equivalent family-routine test. |
| Midsize pickup | Midsize pickup category | Pickup body style and cab layout. |
| Full-size pickup | Full-size pickup category | Pickup dimensions and cab configuration. Do not substitute a cargo van just because both are large. |
| EV | EV category or a clearly identified electric model | Battery-electric powertrain if charging routine is the point of the test. |
| Sedan or hatchback | Matching sedan/hatchback size class | Body style if trunk opening or hatch practicality is one of your questions. |
A simple booking workflow
Before booking: ask for a longer dealer test
A rental is not always the first step. Ask whether the dealer can approve an unaccompanied, overnight, 24-hour, or weekend test drive with enough mileage for your real route. Use the extended test drive guide to compare the dealer, dealer-rental, and conventional-rental options.
1. Write down the questions you are actually testing
Do not begin with “I need something similar to a RAV4.” Begin with the things you need to learn: Will it fit the garage? Can the rear-facing child seat fit without crushing the front passenger? Is the cargo opening workable? Can you tolerate this size every day?
2. Search for the exact model first
If a rental company explicitly offers a guaranteed model that matches what you are considering, that is the cleanest test. Otherwise, assume the booking is category-based unless the company clearly says the exact model is guaranteed.
3. If exact is unavailable, inspect the possible substitutes
Read the category description and example vehicles. Ask whether those possible vehicles preserve the dimensions, body style, seating layout, powertrain, or workflow you need to test.
4. Compare availability across companies
A comparison site can make this faster by showing multiple rental suppliers and categories for the same dates. Use it to identify promising options, then read the actual category details before booking.

If a specific body style, third row, EV powertrain, pickup cab, or other configuration is essential to your test, contact the pickup location before you go. Ask what is likely to be available and whether the configuration you need can be confirmed. Treat any informal assurance as helpful, not as a guarantee unless the booking itself guarantees the model or configuration.
6. Decide at pickup whether the vehicle is still useful
If the assigned vehicle changes the thing you came to test, ask whether another vehicle is available. If not, either narrow the scope of your test or reschedule. Do not force a bad substitute to answer a question it cannot answer.
Examples of a good substitute — and a bad one
- Good: You are considering a compact crossover and receive another compact crossover of similar overall size. Useful for garage fit, parking, loading height, and broad family-space questions.
- Good with limits: You are considering one trim of a model and rent another trim of the same model. Useful for packaging; weaker for ride quality, seats, wheels, engine, and trim-specific features.
- Bad: You want to know whether minivan sliding doors solve your school-drop-off problem, but the rental company offers a three-row SUV.
- Bad: You are shopping for a full-size pickup and use a cargo van as the substitute. Similar exterior bulk does not make it a useful pickup test.
- Bad: You are evaluating EV charging routine and receive a hybrid. It cannot answer the charging question.
Rental details worth checking before you book
- Cancellation and change terms: useful if the assigned category or availability changes.
- Mileage allowance: make sure your planned commute, highway, and errand test fits the rental terms.
- Fuel or charging return policy: know what the rental agreement requires before pickup.
- Coverage choices: coverage varies by rental, location, personal policy, and card benefits. Check the rental terms and your own insurer/card issuer before deciding what coverage you need.
- Pickup inspection: document existing damage and the starting fuel or charge level according to the rental company's process.
Once you have a useful rental, test it properly.
The Weekend Test Drive Checklist turns the rental into a repeatable real-life test instead of an expensive joyride.

- What does “or similar” mean when renting a car?
- It normally means the booking reserves a vehicle class rather than the example make and model. Treat a model as guaranteed only when the offer explicitly identifies it as guaranteed.
- Is another vehicle in the same rental category always a good substitute?
- No. Same-category vehicles can still differ in dimensions, seating layout, visibility, controls, ride, cargo shape, and powertrain. Decide whether the assigned vehicle preserves the particular thing you wanted to test.
- Can I ask for a specific vehicle at pickup?
- You can ask whether a closer match is available. Availability and local policies vary, so treat that as a request rather than a guaranteed booking unless the company explicitly guarantees the model.
- What if the rental has a different trim?
- That can still be useful for basic packaging and daily routine. Verify trim-specific seats, suspension, wheels, engine, driver-assistance features, and equipment separately before buying.
- Do I have to use the Discover Cars link?
- No. The method works regardless of where you book. Use whichever rental source gives you the clearest match, terms, pickup location, and total price for your dates.
