How Our First Car Fit Score Works
Last updated: June 2025
Every car on TheirFirstCar.com receives an Overall Score from 0–100. It answers one question: how well does this car fit a first-time teen driver?
The score is not a general quality score. A sports car can be excellent — and still score low here, because it is a poor choice for a new driver. We weight the factors that matter most when an inexperienced driver is behind the wheel.
Score components
Overall Score = weighted average of four factors
Safety
NHTSA 5-star overall crash test rating, IIHS safety category ratings, electronic stability control, standard side airbags, and the availability of modern safety technology (auto emergency braking, lane keeping assist). This is the dominant factor — a car that fails on safety cannot score well overall, regardless of how reliable or cheap it is.
Reliability
Consumer Reports owner-satisfaction and reliability data, J.D. Power dependability scores, and known long-term reliability issues for the specific model generation. Reliability matters for first cars because parents and teens typically cannot afford unexpected repair bills, and a stranded new driver is a safety risk.
Insurance cost tier
How the car is classified by the insurance industry relative to other cars in our list. Cars with lower horsepower, stronger IIHS ratings, and less theft risk tend to cost less to insure for a teen driver. We use a relative tier (Low / Average / High) based on insurance industry indices and comparison-service data.
Practicality for new drivers
Visibility, parking ease, driver feedback, and forgivingness — how easy the car is to manage when you are still learning. A car with poor rear visibility or a very stiff suspension is more stressful and less safe in new-driver hands, even if it is technically reliable.
What the score is not
- Not a general quality score. Many excellent cars score below 80 here because they are overpowered, sporty, or expensive to insure — all of which are relevant disqualifiers for a first car.
- Not a star rating from NHTSA or IIHS. We incorporate those ratings but the Overall Score is our own calculation.
- Not a price ranking. Price factors in via insurance cost tier and our eligibility criteria, but a cheaper car does not automatically score higher.
Automatic disqualifiers
Certain vehicles cannot appear on TheirFirstCar.com regardless of their raw scores:
- Full-size pickup trucks or body-on-frame SUVs over a certain size
- High-performance or sports variants (e.g., Honda Civic Type R, Subaru WRX STI)
- Vehicles with an NHTSA overall rating below 4 stars or a failing IIHS rating in a major category
- Vehicles with well-documented major reliability problems in the applicable model years
Score updates
Scores are updated when NHTSA or IIHS publish new data, when a major reliability trend becomes well-documented, or when a model year revision materially changes the car's standard safety features. We note the data vintage where relevant.
