What is a good deal score for a used car?

A good deal score is 70 or above. Scores of 70-79 indicate a decent deal, 80-89 is a great deal, and 90-100 is exceptional. Scores below 70 suggest the asking price is above market value.

What factors affect used car value the most?

The top factors are: 1) Mileage relative to age, 2) Vehicle history (accidents, title status), 3) Condition (interior/exterior), 4) Market area demand, and 5) Service records. Price vs. comparable vehicles in your area is the single most important factor.

How accurate is the Deal Score?

Our Deal Score is based on real market data from millions of listings and accounts for regional price variations. It provides a data-driven baseline — always get a pre-purchase inspection and run your own comparables.

Should I always trust the lowest price?

No. Unusually low prices often indicate problems: salvage title, hidden damage, dealer tricks, or vehicles that won't pass inspection. If a deal seems too good to be true, it probably is. Always verify the vehicle history independently.

Is This Car a Good Deal?

Q: What red flags should I watch for when buying a used car?

The 5 critical red flags are: 1) Salvage or rebuilt title — indicates major prior damage, 2) Odometer rollback — miles may be far higher than shown, 3) Flood damage — can cause electrical and mechanical issues years later, 4) Lack of service records — indicates poor maintenance, 5) Multiple owners in short period — suggests recurring problems.

What Makes a Used Car Deal Good or Bad?

A good used car deal isn't just about the lowest price — it's about getting fair value for your money. Here's what actually matters:

✓
Price vs. Market Value — Check the vehicle against 5-10 comparable listings in your area. KBB and NADA provide baselines, but real listings tell you what people are actually paying.
✓
Mileage Relative to Age — Average is ~12,000 miles/year. Significantly higher suggests heavier wear. Significantly lower might mean infrequent use (which has its own issues).
✓
Vehicle Condition — Get a pre-purchase inspection ($100-150). Check tire wear, brake rotors, under-hood cleanliness, and any unusual noises.
✓
Vehicle History — Run a Carfax or AutoCheck. Look for accidents, title brands, ownership history, and service records.
✓
Local Market Demand — The same car costs more in areas where that model is scarce. A Toyota Camry in Texas is cheaper than in Maine.

How AutoSavvy's Deal Score Works

Our Deal Score uses a 0-100 scale based on how the vehicle's price compares to market comparables, adjusted for:

✓
Price Position (40% weight) — How does the asking price compare to similar vehicles nearby?
✓
Mileage Adjusted Value (25% weight) — Does the odometer reading match expected wear for the year?
✓
Price Trend (15% weight) — Is this make/model appreciating or depreciating?
✓
Days on Market (10% weight) — Long-listed cars may have hidden issues — or be negotiable.
✓
History Signals (10% weight) — Clean title, service records, and ownership stability.

5 Red Flags to Watch For

These issues can turn a "good deal" into a money pit — or worse, a car that won't pass inspection or can't be registered.

1. Salvage or Rebuilt Title

A salvage title means the insurer declared the car a total loss. Rebuilt titles are repaired salvage vehicles. These can be 20-40% below market — but the hidden damage often exceeds the savings. Proceed with extreme caution or walk away.

2. Odometer Rollback

Check mileage against service records, inspection stickers, and tire age (tires last ~5 years). Discrepancies of 20,000+ miles are common fraud. Request a vehicle history report and verify against DMV records.

3. Flood Damage

Hurricanes and storms bring flood-damaged cars to market. Check for water stains under seats, rust on seat bolts, musty smells, foggy headlights, and wiring harness corrosion. Flood damage can cause electrical and mechanical failures years later.

4. No Service Records

A car with documented oil changes, brake service, and timing belt replacements is worth more. No records = assume deferred maintenance. Ask for receipts or walk — the seller may be hiding neglect.

5. Multiple Owners in Short Period

Three owners in three years is a red flag. Cars that pass through quickly often have recurring mechanical issues the previous owners couldn't resolve. Check the Carfax for ownership timeline.
