Mercedes 600 Grosser Guide

Buy a 600 Grosser on documented M100 V8 files and honest Mercedes paperwork first. State-limousine folklore still sells, but a soft hydraulic pack or vague leftover claim rewrites the budget fast.

For this November 6, 2026 guide I read Car Collector International: Mercedes-Benz 600 Grosser guide and Wikipedia: Mercedes-Benz 600. The mechanical cautions below come from those pages; the order of checks and the questions for the seller are my own practical recommendations. Any price figures in those sources are market snapshots, not a valuation of the car in front of you. So, compare it with recent sales of the same specification and condition. I also kept the advice to things you can see, hear or ask for on a viewing day. If a seller rushes you past a cold start or blocks a lift inspection, treat that as a signal and walk away before you spend report money.

Know SWB LWB and Landaulet carefully

CCI dates 2,677 cars from 1964-1981 with a 6.3-litre M100 V8. Pick a documented car before you travel.

Ask about M100 V8 and hydraulic invoices

CCI wants continuous specialist files. Ask for the last invoice by shop and date.

Confirm body style carefully

CCI treats SWB Saloon, LWB Pullman and Landaulet cars as distinct markets. Match Mercedes paperwork before you bid.

Inspect hydraulics carefully

Soft hydraulic leaks rewrite the budget. Photograph undertrays.

Keep a dated note of the cold start

Write idle quality, gearbox engagement and any smoke. Our cold-start test guide helps you brief that first start.

Prefer continuous Mercedes classic files

CCI puts books and specialist invoices high on the list. Photos beat handshake stories.

Confirm SWB LWB or Landaulet carefully

CCI dates 2,677 cars from 1964-1981 with 2,190 SWB, 428 LWB Pullman and 59 Landaulet cars. Match Mercedes paperwork before any leftover claim.

Ask about M100 V8 and hydraulic invoices carefully

CCI wants continuous specialist files. Ask for the last invoice by shop and date.

Inspect air-suspension and hydraulic systems carefully

Soft hydraulic leaks rewrite the budget. Photograph undertrays before the bay is cleaned.

Keep a dated note of the cold start

Write idle quality, gearbox engagement and any smoke. Our cold-start test guide helps you brief that first start.

Photograph tyre date codes and brake wear

Fresh stickers on old rubber still fail a real ownership budget. Write the DOT week and pad condition.

Ask who can still support the car locally

Confirm a Mercedes classic specialist booking window before you send a deposit.

Budget for Landaulet provenance notes

CCI treats Landaulet state cars as a distinct market. Ask for written provenance before you lock a bid.

Prove the identity before a deposit

Match the chassis number on the Mercedes-Benz 600 Grosser to the title, any import papers and the plate on the car before you order a history report. Our VIN verification guide walks through that match, and imported-car report coverage sets expectations for cars that spent years overseas. Older chassis numbers may sit outside modern report databases, so confirm coverage before paying. NMVTIS covers U.S. title history only; it cannot replace foreign records or a physical inspection.

Get the repair scope in writing first

If the V8 or hydraulic story looks soft, get a Mercedes classic specialist written estimate before you go further. Look, a seller PDF or a folder of photos is a starting document, not independent proof of condition. Ask the inspector for written findings with local estimates, split into safety work and cosmetic wishes. The NYC consumer-agency used-car guidance tells buyers to have an independent mechanic check the car, and our pre-purchase inspection checklist helps you set the scope. Keep a dated note of the drive, the temperatures and any noises, because a seller who disputes your findings later will ask what you saw and when. Keep copies of texts and emails with the seller in the same folder as the PPI write-up so the timeline stays clear.

We are a licensed CARFAX and AutoCheck reseller, not affiliated with CARFAX, AutoCheck or Experian. Guest reports have been about $5.50, member reports about $4.50 and a two-report bundle about $6.75; confirm the price at checkout because it can change. A report can miss unreported work, so keep the inspection appointment even when the history looks quiet.
