Grade 4 vs Grade 3.5 — which should you buy?

Updated August 5, 2026 · 8 min read

Grade 4 is the popular baseline, but Grade 3.5 cars are cheaper and often fine. Here's how to choose without getting stuck with someone else's deferred repairs.

Short version: Buy Grade 4 for easier resale and fewer surprises. Buy Grade 3.5 when the price gap is real, the damage map is honest, and you're happy to keep the car. Always read beyond the number.

Side-by-side

Grade 4Grade 3.5
ConditionGood used; minor cosmetic flawsAverage; noticeable wear, small repairs
Typical buyerResale, low hassle, first importBudget / keepers who accept marks
PriceHigher — the market's “safe” gradeLower — discount should be obvious
Watch forTired interior letter (C/D)W clusters, XX panels, mileage vs year
Risk if you skip the mapPaying Grade 4 money for a tired cabinBuying deferred bodywork at a fake discount

Both grades sit above junk and below near-new. Full scale: auction grades explained. Comparing upward? See Grade 4.5 vs Grade 5.

What Grade 4 actually means

Inspectors use Grade 4 for cars that are solid daily drivers with only minor visible flaws — light scratches, small marks, normal used-car wear. It's the grade most importers quote as “clean” without being as-new. Resale buyers and cautious first-timers usually start here.

  • Expect a few cosmetic marks; don't expect structural repair (that would be R/RA).
  • Check the interior letter — a Grade 4 with a harsh C/D cabin can still disappoint.
  • Confirm mileage fits the year; Grade 4 does not prove the odometer is honest.

What Grade 3.5 actually means

Grade 3.5 is a step down: more visible wear, possibly small panel repairs, and a price that should reflect that. It is not automatic “bad car” territory — plenty of 3.5 cars are honest high-use vehicles. The grade is a summary; the damage map is the detail.

  • Look for clusters of W (repair wave) marks — one W1 is noise; a row of W2/W3 is a story.
  • XX on bolt-on panels (doors, bumpers) is common; don't confuse it with an R grade.
  • If the discount vs a similar Grade 4 is tiny, pay for the 4 instead.

How to decide for your situation

Your situationLean toward
First Japanese import / want easy resaleGrade 4
Tight budget, will keep 5+ yearsGrade 3.5 if the map is clean
Planning bodywork / wrap / project useGrade 3.5 can be smart
Dealer flipping next yearGrade 4 (or 4.5+)
Seller won't share a verifiable sheetNeither — walk

The checks that matter more than 4 vs 3.5

  1. Verify the original sheet by chassis number — edited grades are common.
  2. Read the damage map with the overall grade, not instead of it.
  3. Compare mileage to interior wear and year — see mileage guidance and letter grades. Neighbour comparisons: 4 vs 4.5, 3 vs 3.5.
  4. Price the discount in your market — a 3.5 that costs almost Grade 4 money is a bad trade.
A clean Grade 3.5 with a transparent map often beats a Grade 4 you're stretching to afford. A Grade 4 with a suspicious sheet beats a cheap 3.5 you can't verify.

Check the real grade first

Verify the original auction sheet by chassis number before you choose 4 or 3.5.

Frequently asked questions

What does auction grade 3.5 mean?
Grade 3.5 means average used condition — more wear and possibly minor repairs than Grade 4. It is not automatically a bad car; verify the damage map and make sure the price clearly undercuts Grade 4.
Is Grade 3.5 bad?
No — it's an average used car with more wear and possibly minor repairs. It can be good value if the damage map is clean and the price clearly undercuts Grade 4.
Is Grade 4 always worth the extra money?
Often for resale and peace of mind, but not if the premium is large and a verified 3.5 shows only cosmetic issues you're fine living with.
Can a Grade 3.5 have accident history?
Structural accident history is usually graded R or RA, not 3.5. Still read the map for heavy W marks and replaced panels.
Should I buy Grade 3.5 for a family daily?
Yes if the verified sheet looks honest and you've budgeted for cosmetics. If you want the lowest drama, stretch to Grade 4.
