What actually makes a good used car?
Used car buyers waste money on the wrong cars because the industry measures the wrong things. A good used car is the one that will not strand you, will not bankrupt you to insure, will protect you in a crash, will do the job you bought it for, and will be cheap to fix when it eventually breaks. We score every used vehicle generation on those five dimensions and let the data tell you which ones qualify.

The five things that actually matter
Reliability
Will it strand you?Composite of RepairPal rating, unscheduled repair visits per year, severe issue probability, 250,000-mile survival rate, and annual repair cost. Anchored against the real range of our fleet, not a marketing claim.
True annual cost
What it actually costs to keep on the road.Fuel at current US average prices, insurance for both a 25-year-old male and a 40-year-old female (averaged), maintenance, tires, and oil changes. One number so the Civic and the M3 compete on the same axis.
Safety
Will it protect you in a crash?NHTSA crash stars plus IIHS rating plus electronic stability control availability. Frame rust caps the score at 6 because crashes on a rusted frame are uniquely dangerous.
Practicality
Will it actually do what you need?Segment-relative. A truck and a sports car do not compete on cargo. Truck practicality scores tow capacity and bed, SUV practicality scores seats and cargo, sports practicality scores driver focus.
Repairability
What happens when it breaks?Headlight assembly cost as the universal benchmark. Every car needs one, and the cost predicts everything from suspension to electronics. Penalized for dealer-only parts and discontinued part numbers.

Special-purpose tags for different used car buyers
The five sub-scores answer one question: is this a good used car. These tags answer different questions for different buyers.
Five criteria specific to new drivers: safety score 7.5 or higher, annual insurance for a 25-year-old male under $2,200, repairability score 7.0 or higher, NHTSA rollover risk 18% or lower, and parking-friendly dimensions (length under 190 inches, width under 74 inches, turning circle under 38 feet). Hybrids qualify. The Toyota Prius is one of the best first used cars made.
Used vehicle generations that score in the top 25% of their segment but are not the obvious mainstream pick everyone already recommends. Mazda Miata generations, Land Cruiser 100 Series, Honda Ridgeline 1st Gen, Toyota Sienna middle generations. The Camry is excluded by definition because every used car list already has it.
Composite score in the top quartile relative to typical asking price. Different from hidden gem. A budget pick can be a mainstream car that depreciated heavily and now offers exceptional used market value.
NHTSA rollover risk above 20% or tipped during dynamic testing. Mostly tall body-on-frame SUVs and 2-door Jeep Wranglers. Still recommendable for off-road buyers who understand the trade-off.
Used cars we will not recommend regardless of how popular they are
Some used cars never make any list here, regardless of how loved they are on enthusiast forums or how cheap they appear on the used market. The criteria are mechanical, not opinion-driven:
- Frame rust on body-on-frame trucks and SUVs from rust-belt states. Frame repair costs more than the truck. A safety cap of 6 and a true annual cost cap of 5 reflect this.
- Used generations with severe issue probability above 20%. Audi Q7 4L, Jeep Grand Cherokee WK2, and a few others fall here. The composite score reflects it.
- Used vehicles with active stop-sale recalls. Surfaced in the pre-purchase inspection checklist.
- Generations with incomplete data. A used vehicle cannot enter the live database without all five sub-scores populated. Gaps would mean shortcuts.
Frequently asked questions about buying used cars
What makes a used car a good buy?▾
A good used car is reliable enough to not strand you, cheap enough to actually keep on the road (insurance plus maintenance plus fuel), safe enough to protect you in a crash, practical enough to do the job you bought it for, and repairable when it eventually breaks. We score every used vehicle generation on those five dimensions from 0 to 10 and combine them into a 0 to 100 composite. The weights vary by segment because a commuter car and a truck are not competing on the same criteria.
How do you measure used car reliability?▾
Reliability is a weighted composite of RepairPal rating (30%), unscheduled repair visits per year (25%), severe issue probability (25%), 250,000-mile survival rate (15%), and annual repair cost (5%). We normalize each input against the real observed range across our fleet, not a marketing claim, then map the output to a 3.0 to 10.0 scale rounded to the nearest 0.5.
What should I look for in a used car before buying?▾
Pull a Carfax and an AutoCheck report. Confirm the title is clean and in the seller name with no liens. Inspect the frame and undercarriage for structural rust. Check the oil and coolant condition. Test drive cold to listen for timing chain rattle. Run an OBD2 scan for pending codes. For a full vehicle-specific inspection checklist tailored to the exact engine, transmission, and drivetrain, use our pre-purchase inspection generator on any vehicle detail page.
What used cars should I avoid?▾
Avoid body-on-frame trucks and SUVs from rust-belt states with frame rust. Avoid generations with severe issue probability above 20% (Audi Q7 4L and Jeep Grand Cherokee WK2 are examples). Avoid cars with active stop-sale recalls. Avoid any vehicle the seller will not let you inspect or run a VIN history report on.
Are luxury used cars worth it?▾
Luxury used cars are worth it for buyers who can absorb dealer-only parts pricing and higher insurance. Most luxury generations in our database have lower composite scores than their non-luxury counterparts because the repair cost dominates the cost of ownership over a 5-year hold. The Lexus LX 470 is a notable exception. The luxury segment uses a weighting that emphasizes reliability and safety more than practicality.
What is the difference between reliability and repairability?▾
Reliability measures how often something breaks. Repairability measures what it costs and how feasible the repair is when something does break. A car can be unreliable but cheap to fix (older Subaru Outback with EJ25 head gasket), or reliable but expensive to fix (older BMW with a chain stretch). Both matter for total cost of ownership, which is why we score them separately.
Do you accept money from dealers or manufacturers?▾
No. We have no financial relationship with any dealer, manufacturer, or car-buying service. No lead fees, no referral commissions, no sponsored placements, no paid score adjustments. The site runs on Google AdSense and clearly disclosed affiliate links in our Modernize section for accessories like CarPlay head units. Those affiliate links never touch vehicle scoring.
What we never compromise on
Scores are formula-driven from raw data. The formulas do not know what we link to in the modernize section, who pays for ads on the page, or which used car the editor personally owns. The wall is structural, not promised.
Every audit we run on the database catches the same thing: every stored score matches what the formula would produce from the inputs. If you spot a number that looks wrong, tell us. The fix is to correct the input data or the formula, not the score.
