Diesel vs Electric: Which Country Has the Better Supply, Based on Its Local Market (2026)

Germany: the deep diesel market

The German vehicle parc keeps a far higher share of diesel cars than the European average, particularly in saloons, large estates and premium SUVs, where diesel remains the preferred engine for anyone covering high annual mileage. That translates into a wider selection of 2 to 5-year-old diesel units, often with strong service histories from corporate fleets and sales representatives who racked up serious motorway miles.

Netherlands: Europe's most mature used-EV market

The Netherlands spent well over a decade running strong tax incentives for electric-vehicle purchases, which built the densest EV parc in continental Europe relative to the country's size — battery-electric cars accounted for roughly 30% of new registrations in early 2026. The BPM registration-tax exemption for new EVs ended in 2025 and a flat fee now applies to new purchases, but that change concerns buying new in the Netherlands; it has no bearing on Spanish IEDMT, and it does not shrink the large pool of three-to-six-year-old used EVs already on Dutch roads. The result is a used-EV market meaningfully more mature than Germany's, France's or Belgium's: more units available, more model years to choose between, and sellers more accustomed to documenting real battery condition (State of Health reports).

France and Belgium: a middle ground

France has historically leaned diesel in the family-car segment, similar to Germany though with less weight in the premium tier, and a growing but still smaller EV share concentrated mostly in city cars and Renault-Stellantis-group models. Belgium, with its triple linguistic and commercial influence, blends both trends without the sharp specialty its neighbours show.

Tax rules: why fuel type changes the IEDMT bill so much

IEDMT, Spain's registration tax, is calculated on the car's WLTP CO2 figure regardless of where you bought it: 0% up to 120 g/km, 4.75% for 121-160, 9.75% for 161-200, and 14.75% above 200 g/km. An electric car at 0 g/km is always exempt, while a high-end diesel above 160 g/km can land in a considerably more expensive band. This difference should always be added to the purchase price when comparing options, whichever of the four countries the car comes from.

What to check depending on what you are buying

• Diesel: real mileage, timing belt/chain history, and the condition of the particulate filter (DPF).
• Electric: battery State of Health report, history of frequent fast charging, and a transferable battery warranty.
• Either way, always request the periodic roadworthiness report from the country of origin (TÜV, contrôle technique, APK or autokeuring depending on the country).

Hunting for a diesel in the Netherlands or an EV in Germany is not impossible, but you will be swimming against the grain of the local market itself.
