How we research, rate, and review
Where our facts come from, and the process each car goes through before it earns a review.
Why sourcing matters here
Marketing copy spreads faster than fact. A confident forum post is not the same as a verified figure.
On a site where a claim can steer a five-figure purchase, the gap between a good source and a bad one is real money in your pocket.
Think about what a single wrong number can cost.
An overstated fuel-economy figure looks harmless. Then you multiply the gap by fifteen thousand miles a year for a decade.
A safety claim that leans on an old test can send a family toward a car that no longer earns the rating it used to.
A reliability line pulled from a fan forum tells you how one owner feels, not how a thousand cars held up.
So every review here is built from references that each do one job well. We lean on each only for what it is genuinely authoritative about.
Four steps from spec sheet to review
Fix the facts
We pull specifications, fuel economy, and safety ratings from EPA, NHTSA, and IIHS before writing anything. Opinion never gets ahead of the data.
Road-test the claims
A road tester drives the car and checks how the numbers feel in real conditions. A quiet-cabin figure or a brochure ride quality either holds up or it does not.
Reliability and problems
We document the reliability record and the faults owners report. We rate conservatively when the picture is mixed rather than rounding up.
Expert review
An ASE-certified technician checks each buying-advice page, confirms the sourcing, and dates the review before it publishes.
Matching the source to the claim
No single reference answers every question.
The skill is knowing which source proves which claim, and never stretching one beyond what it can carry.
This is the exact mapping we hold ourselves to.
| Source type | Authoritative for | How we use it |
|---|---|---|
| EPA fuel economy data | MPG, range, efficiency | Ground every economy figure we publish |
| NHTSA | Recalls, crash ratings, complaints | Report safety scores and flag open recalls |
| IIHS | Crashworthiness, crash avoidance | Confirm independent crash performance |
| Reliability studies | Long-term dependability | Frame the reliability section, not one owner's story |
| Manufacturer spec sheets | Dimensions, powertrain, warranty | Confirm the hard specifications |
How to read a claim on our pages
Where a review makes a specific economy, safety, or reliability claim, it points to where that figure comes from. A number you can trust names its source.
Whenever you check any source, ours or anyone else's, look for these three things.
- A named institution, not an anonymous forum post
- A date, so you can judge whether the figure is still current
- A scope that actually covers the trim and model year in question
If a claim fails any of those tests, treat it as a lead to verify, not a fact to act on.
That is the same standard we hold ourselves to before a figure reaches your screen.
How our ratings scale works
A rating is a summary of evidence, not a gut feeling.
We weigh measured data first. Safety scores, fuel economy, and the documented reliability record carry more weight than subjective impressions.
Driving feel and cabin quality matter, but they sit on top of the hard numbers, not in place of them.
We also rate conservatively on purpose. When the evidence is mixed, when a reliability record is short, or when a known fault is serious, we round down and say why.
The cost of an overstated rating falls on the buyer, so we would rather understate a good car than oversell a risky one.
A cautious score with a clear reason behind it beats a generous one you cannot trust.
Concretely, a headline rating never rests on a single strength. A car with a brilliant engine but a fragile transmission does not earn a top score, because the transmission is what strands an owner and empties a wallet.
A model that reviews well on launch but has no reliability history yet is rated on what we can prove, with a clear note that the long-term picture is still forming.
When a recall is open or a safety score slips against newer, tougher tests, that pulls the rating down until the issue is resolved.
The goal is plain. A high score here is hard to earn and therefore worth trusting, not handed out to keep manufacturers happy.
Every rating is also dated. A car we rated two model years ago may have been revised, recalled, or overtaken by a stronger rival, so the review date tells you how fresh the judgement is.
If the evidence behind a score changes in a way that matters, we revisit the rating rather than leave an old verdict standing.
The limits of any source
Good sourcing makes a review accurate. It cannot make a review a substitute for seeing the actual car.
A national safety rating describes a model, not the specific vehicle with a hundred thousand miles and a repaint over one door.
A reliability study describes an average, not the one example that was neglected or the one that was babied.
Our figures tell you what to expect and what to look for. They cannot tell you the condition of the car in front of you.
That gap is exactly why the last step of buying is never on a website.
Use our research to build a shortlist and to know which faults to check for. Then close the gap with a test drive and an independent inspection.
Sources also age, and we treat that as a live problem rather than a footnote.
A safety rating can be superseded when a testing body toughens its standards, an economy figure can change with a new engine, and a reliability record fills in only as a model spends years on the road.
When the reference behind a claim is updated, we update the claim. A figure that was accurate three years ago can quietly mislead a buyer today.
Good sourcing is not a one-time act at publication. It is the ongoing work of keeping each figure honest against the best current data.
No source replaces a test drive
These references make our reviews accurate. They cannot replace driving and inspecting the actual car before you buy.
