Grade 4.5 vs Grade 5 — is the upgrade worth it?
Grade 5 looks better on paper. Grade 4.5 is often the smarter spend. Here's how to choose without overpaying for polish you'll stop noticing in a week.
The difference in plain English
Grade 5 is essentially as-new condition with very low mileage. Grade 4.5 is excellent used condition — light use, usually still under roughly 100,000 km, with only minor cosmetic history. Both sit above the everyday Grade 4 baseline.
| Grade 4.5 | Grade 5 | |
|---|---|---|
| Condition | Very good, light use | As good as new |
| Typical mileage | Often under ~100,000 km | Usually very low |
| Price | Premium over Grade 4 | Highest everyday premium |
| Best for | Value + pride of ownership | Near-new without buying new |
When Grade 5 is worth it
- You specifically want near-new condition and will keep the car a long time.
- The price gap to 4.5 in your market is small.
- The Grade 5 sheet also shows strong interior/exterior letters (A/B).
When Grade 4.5 wins
- The Grade 5 premium is large for cosmetic differences you won't feel daily.
- You care more about a clean damage map than a headline number.
- Budget is better spent on a newer year or better options at 4.5.
