Engine & drivetrain
Its 4.0-liter twin-turbo V8 makes 603 hp and 627 lb-ft, with temporary EQ Boost assistance and a nine-speed transmission driving 4MATIC+ AWD.
Trim differences
Separate options from maintenance condition when comparing advertisements. An attractive brake or wheel upgrade can also change replacement costs substantially.
Interior & seating
The guide lists dual 12.3-inch displays. Its third-row package applies to the GLE 53, not this GLE 63 S specification.
Efficiency & range
Calculate fuel expense using the exact model-year rating and your mileage. Mild-hybrid assistance should not be interpreted as plug-in driving capability.
Safety & equipment
Ask a qualified inspector to check suspension, brakes and tire condition before demonstrating performance. A fault-free display alone does not establish mechanical readiness.
Strengths
Its appeal is combining this particular V8 drivetrain with SUV access. That is a narrower and more defensible reason to buy than expecting inexpensive practicality.

Considerations
Obtain replacement quotes for the tires and fitted brake type before paying a deposit. Those numbers can change which used example represents better value.
Recommended use
An owner carrying passengers should evaluate their entry and seating comfort before judging the vehicle from the driver's seat alone.
Rivals & related
Compare a GLE 53 if the cabin and body are the attraction, and a performance sedan if the raised body is not essential.
