A diesel car at 10,000 km a year

Short commutes or a second car; the car spends most of its life parked. Here is what that does to a diesel car.

The shape at 10,000 km for Diesel

At this distance the car is almost entirely a depreciating asset. Depreciation dwarfs energy and maintenance, which makes any structure that finances only the depreciation — PCP, lease, salary sacrifice — comparatively efficient, and makes an expensive-to-buy, slow-to-depreciate car a worse idea than it looks. [1]

Powertrain and distance together. A line that is heavy for both Diesel and this mileage is the one this driver should decide on. Ordinal combination consistent with the total-cost-of-ownership literature cited on this page.

Which way to pay fits Diesel at 10,000 km

How well each financing structure fits 10,000 km a year A bar chart grading each financing structure from 1 (poorly suited) to 4 (well suited) for a driver covering 10,000 km a year.

Fit at 10,000 km a year. Structures with a mileage cap — lease, PCP, subscription — fall away as distance rises; outright ownership climbs. This is the comparison the monthly figure hides. Grading: our reading of how each structure’s terms behave with distance, not a formal assessment.

The Diesel specifics at this distance

Efficient at sustained speed; the classic long-distance economy case still holds on fuel alone.

Defensible only for a genuinely high-mileage motorway driver outside restricted cities, and increasingly hard to justify even there once the residual and access risks are priced.

Is a diesel car worth it at 10,000 km a year?
Defensible only for a genuinely high-mileage motorway driver outside restricted cities, and increasingly hard to justify even there once the residual and access risks are priced. At this distance the car is almost entirely a depreciating asset.
Should I lease a diesel car at 10,000 km a year?
A reasonable fit at this distance. Mileage caps on leases and PCP will not bind, so the cheapest allowance is fine — but the guaranteed future value assumes it, and going over changes the deal.
