Used Mercedes-Benz MB100 Headrest

Yes, the MB100 (sold in the UK roughly from the late 1980s through to the mid-1990s) did come with front seat headrests on at least some trim and seat configurations, as it was offered both as a panel van and as a people-carrier/minibus with various seat arrangements. Rear headrests, however, are far less consistent and depend heavily on the specific seat configuration fitted to your vehicle. If you are looking for a rear headrest, confirm with the breaker exactly which seat type your MB100 has, as configurations varied considerably.

The MB100 had a relatively long and largely unchanged production run in Europe, but there were detail changes to seat and trim specifications over the years that can affect headrest post dimensions and seat-back slot patterns. There is no widely documented major facelift with a clean before-and-after cutoff point for UK-market vehicles, so year-to-year interchangeability is genuinely uncertain. Give the breaker both your registration and the donor vehicle's year so they can compare seat specifications before you commit.

Yes, trim and seat specification do matter here - the MB100 was offered with different interior and seating packages depending on whether it was a basic panel van, a window van, or a minibus/people-carrier variant, and seat styles varied accordingly. A headrest from a basic van seat will not necessarily fit a higher-spec or minibus-style seat even from the same year, because the post diameter, spacing, and seat-back receiver can differ. Tell the breaker your trim or body-use type as well as your registration so they can match the correct seat family.

For front seats on the MB100, the driver (OS) and front passenger (NS) seats were often different units with different seat frames, so the headrest posts and receivers may not be interchangeable between sides. If you are replacing a specific side, tell the breaker clearly whether you need NS (passenger, left) or OS (driver, right) to avoid ending up with a non-fitting part. For bench or individual rear seats the distinction is less likely to matter, but again confirm with the breaker against your exact seat configuration.

No - the engine has no bearing on interior seat or headrest fitment whatsoever. What matters is the seat type, trim or interior specification, and the position (front or rear, NS or OS), not whether your MB100 has a petrol or diesel engine. Focus your conversation with the breaker on the interior specification rather than the drivetrain.
