The short answer
- Normalize the periodDo not compare 24 and 36 month totals as if they buy the same duration.
- Keep upfront cash visibleInitial payments and establishment fees can reverse the apparent monthly advantage.
- Compare permitted useMileage, excess charges, service and return conditions determine what the price actually covers.
- Preserve the wordingRecord the exact source for each number and mark anything missing as unknown.
A synthetic comparison
The offers below are fictional. They demonstrate the calculation and can be downloaded for testing without exposing anyone's documents.
Standard: EUR 2,394 + (EUR 399 × 36) + EUR 300 = EUR 17,058. Flex: EUR 918 + (EUR 459 × 24) = EUR 11,934. These totals cover different periods, mileage and service, so they do not establish an overall winner.
Normalize without overwriting the offer
For orientation, the Standard fixed commitment is EUR 473.83 per contracted month and the Flex fixed commitment is EUR 497.25 per contracted month. That calculation still does not price the additional mileage allowance, excluded service, possible wear charges, insurance, tax changes or early termination.
Keep normalized calculations beside the original terms. Never replace the source values with a derived number that cannot be traced back to them.
Questions to resolve before choosing
- Is the initial payment refundable, a deposit, or simply an advance payment?
- Does the quoted monthly payment include tax, registration and establishment fees?
- How is excess mileage calculated and when is it charged?
- What service and maintenance are included, and who pays for tyres or damage?
- What counts as acceptable wear at return?
- Can the agreement be ended early, transferred or extended?
- Is the vehicle specification genuinely comparable?
Use Aelipsis carefully
Choose Compare alternatives when the sources describe different vehicles or offers rather than revisions of one agreement. Quick check compares supported labeled terms that appear in both sources. Missing information remains unknown, and the tool does not calculate lifetime cost or select the best vehicle.
For conditions outside Quick check's supported terms, use the source excerpts as a review plan or explicitly choose Hosted AI after reading the transfer disclosure. Always verify the original lease documents before relying on a finding.
