March 2026 Market Report: Spring Rally Begins
March 2026 marks the beginning of the classic spring buying season on the European used car market. As temperatures rise and buyer enthusiasm builds, positive price signals are emerging across several segments — particularly in roadsters and established classics. This market report, based on data as of March 30, 2026, analyzes price movements across 18 key models from BMW, Mercedes-Benz, and Audi.
Market Overview: March 2026
The overall market shows a two-tier pattern this month. Youngtimers and sporting models are benefiting from the seasonal uplift in demand, while higher-volume daily classics face continued price pressure. Listing activity remains robust — the BMW Z3 alone shows 90 active listings, indicating a highly liquid market with real choice for buyers.
The strongest price gains in March came from the BMW Z3 (up approximately 7% from its March low to €16,235), the Mercedes W210 (up approximately 6% year-to-date to €7,845), and the Mercedes W126 (up 4% to €21,638). These movements fit the classic spring pattern: convertibles, roadsters, and collector-grade classics attract premium buyers as the driving season begins.
On the other side, everyday classics such as the Audi C6 and B5 continued their mild downward drift — a sign of well-supplied markets without seasonal demand catalysts.
Current Prices in Detail
BMW
BMW’s lineup continues to offer strong diversity from accessible youngtimers to serious collector cars.
| Model | Average Price | Price Range | Trend | Listings |
|---|---|---|---|---|
| E39 5 Series | €7,467 | €1,200 – €21,990 | → | 82 |
| E36 3 Series | €8,693 | €1,150 – €28,900 | ↘ | 66 |
| E46 3 Series | €15,778 | €1,200 – €520,000 | ↘ | 65 |
| Z3 Roadster | €16,235 | €4,000 – €48,500 | ↗ | 90 |
| E38 7 Series | €16,288 | €1,750 – €42,500 | ↗ | 81 |
| E30 3 Series | €22,774 | €4,000 – €59,999 | → | 68 |
| E39 M5 | €36,600 | €24,000 – €48,500 | ↗↗ | 5 |
The E38 7 Series remains one of the most attractive propositions in the classic BMW market: 81 listings, an average of €16,288, and a confirmed upward trend. This executive saloon from 1994–2001 is increasingly recognized as a design and engineering milestone, and prices have responded accordingly over the past 12 months.
The standout mover, however, is the E39 M5. With just 5 listings and an average of €36,600 — and a strongly positive price trend — this is a textbook supply-constrained market. The E39 M5 represents BMW’s last analog M car with a high-revving V8, and collector demand is outpacing available supply. Buyers who have been waiting may find the entry price has risen significantly by summer.
The Z3 Roadster is the clearest seasonal story of March: its average touched a low of €15,181 in early March before climbing back to €16,235 by month end. With 90 active listings it remains the most liquid BMW model we track — and the most seasonally sensitive.
Mercedes-Benz
| Model | Average Price | Price Range | Trend | Listings |
|---|---|---|---|---|
| W210 E-Class | €7,845 | €1,250 – €49,500 | ↗ | 71 |
| W124 E-Class | €14,397 | €1,250 – €123,456 | ↘ | 89 |
| W140 S-Class | €17,502 | €2,850 – €45,000 | ↘ | 85 |
| W126 S-Class | €21,638 | €3,500 – €109,000 | ↗ | 59 |
| R129 SL | €25,276 | €8,500 – €52,241 | ↘ | 69 |
| R107 SL | €34,867 | €11,900 – €79,995 | → | 63 |
The W140 S-Class holds the highest listing volume among all Mercedes classics in our database at 85 active offers. The current average of €17,502 is slightly softer than last month, reflecting increased supply without a proportional increase in demand. Yet the price range — €2,850 to €45,000 — tells the real story: condition and history matter enormously here, and exceptional examples continue to command strong premiums.
The W210 E-Class deserves particular attention. Up roughly 6% since January, it is quietly establishing itself as a rising star in the affordable classic segment. The W210’s historical reputation for rust problems has been effectively filtered out of the market — what remains at today’s prices are predominantly well-maintained, rust-treated examples. At €7,845 average, it offers excellent value.
The R107 SL holds steady at €34,867 with 63 listings. This 1971–1989 classic remains one of the most stable stores of value in the Mercedes lineup, unaffected by the price corrections seen in more recent models.
Audi
| Model | Average Price | Price Range | Trend | Listings |
|---|---|---|---|---|
| C6 A6 | €5,489 | €1,650 – €13,000 | ↘ | 27 |
| B5 A4 | €7,338 | €1,300 – €59,000 | ↘ | 44 |
| D2 A8 | €10,203 | €1,200 – €34,990 | ↗ | 38 |
| RS4 B5 | €48,011 | €12,345 – €88,900 | ↘ | 18 |
| Ur-Quattro | €109,900 | – | – | 2 |
The D2 A8 is the positive surprise from Audi this month. At €10,203 with an upward trend and 38 active listings, the aluminum-spaceframe luxury saloon from Neckarsulm appears to have found its floor. Once overshadowed by more glamorous competitors, the D2 is increasingly appreciated for its pioneering Audi Space Frame construction, quad-turbocharged diesel options, and executive presence at a fraction of its original cost.
The RS4 B5 remains locked in the premium collector bracket at €48,011. The mild downward price pressure should be interpreted cautiously: with only 18 listings, a single high-mileage example entering or leaving the market can shift the average by thousands. The long-term trajectory for the RS4 B5 remains firmly upward.
Spring Market Patterns
March 2026 follows the historical spring pattern closely:
Roadsters and convertibles are the clearest seasonal plays. The Z3 gained over €1,000 in March alone. Buyers who purchased in January or February — when prices touched winter lows — are already sitting on paper gains. The seasonal premium for these cars typically peaks in April and May.
Established classics like the E30 at €22,774 maintain elevated prices year-round but show less seasonal volatility than open-top cars. The E30 has firmly graduated from “old BMW” to “collector car” in market perception.
Everyday youngtimers — E39, C6 — show little spring effect. These functional classics are bought and sold throughout the year for practical reasons, and their pricing follows supply and demand fundamentals rather than seasons.
Mileage and Condition Analysis
Average mileage figures across our tracked models remain high in March 2026. The E39 5 Series averages 202,403 km, the W124 189,475 km, and the C6 A6 a substantial 268,267 km.
In practical terms, the mileage premium — the price difference between a 150,000 km example and a 250,000 km example — runs 30–50% on these models. For the W140 S-Class (average 176,850 km), the €2,850 to €45,000 price spread directly reflects this differential, along with condition and documentation.
Well-documented cars with full service histories typically command a 15–25% premium over the market average in spring. If you are looking for an exceptional example, now — in the early spring weeks — is the time to act before summer narrows the selection and prices climb further.
April 2026 Outlook
Rising prices expected: Roadsters and open-top classics (Z3, R107 SL, R129 SL) should continue their seasonal climb through April. Historical patterns suggest the peak is reached in late April to mid-May.
Stable prices expected: The E38 7 Series and D2 A8 show solid fundamentals with no indication of sharp moves in either direction. Gradual appreciation is the more likely scenario.
Watch closely: The RS4 B5 — at just 18 listings, this market is thin and any significant transaction can move the average. Interested buyers should monitor daily.
