A car can have enough passenger seats and still be the wrong choice for your luggage. Before choosing a sedan, SUV or Mercedes V-Class, count everyone travelling, list every bag and include the items that do not behave like suitcases: a folded stroller, golf bag or mobility aid.

Summit supplies the vehicle and chauffeur together. The figures below are the passenger and luggage counts shown for three actual models in the Summit fleet, checked on 9 October 2026. They are a starting point for choosing a category, followed by a capacity check for the vehicle allocated to your booking.

What Summit currently lists

Passenger figures exclude the chauffeur.

Vehicle	Passengers	Suitcases
BMW 735i sedan	Up to 3	3
Cadillac Escalade ESV SUV	Up to 6	5
Mercedes-Benz V300, the V-Class option	Up to 7	6

These are representative listing figures, not a guarantee that the maximum passenger count and suitcase count fit simultaneously in every configuration. Summit's public listings do not specify a standard suitcase size, measured boot dimensions, loading-opening dimensions or the seating layout for every allocated car. Confirm the complete load with the operations team before booking.

When a sedan is a sensible starting point

For one or two travellers, a BMW 735i is worth considering if the luggage fits. Two passengers with two cases and small hand luggage present a different loading question from three passengers with three large rigid cases.

Do not use the third passenger seat as an assumed luggage allowance. A seat needed for a passenger or child restraint must remain available for that purpose, and baggage needs suitable stowage. Send the case measurements instead of relying on the description “three suitcases”.

When to consider an SUV

The Escalade ESV's listed capacity makes it a candidate for a larger party, but confirm that the required seats can stay usable with all the luggage loaded. A cargo-volume figure with seats folded, even if found elsewhere, would not answer that question when your passengers need those seats.

Also check the exact model. Summit lists a separate Escalade ESV Facelift, while its Mercedes-Benz GLS600 Maybach has an executive configuration listed for up to three passengers. “SUV” does not mean that every vehicle takes six passengers.

When a Mercedes V300 is worth checking

The V300 is the people-carrier option in this comparison. Its listing of up to seven passengers and six suitcases can help shortlist a vehicle for a family or group, but seven people with six large cases, cabin bags and a stroller still require an operational check.

Ask how your group will be seated, where the luggage will go and whether child seats affect access to other seats. Do not assume a particular seating layout, removable seat, luggage partition or child-seat anchorage from a generic V-Class brochure. The allocated Summit vehicle needs to suit the actual booking.

Measure bags in a way the booking team can use

For each suitcase, send external height × width × depth in centimetres, including wheels and handles. If it will be expanded, measure it expanded. Count cabin cases, laptop bags and shopping bags as well as checked luggage.

A useful example of a luggage list is:

Two rigid cases, each 75 × 50 × 30 cm, including wheels and handles.
Two cabin cases, each 55 × 40 × 23 cm.
One stroller, with its actual folded measurements supplied separately.

Those numbers are illustrative bag dimensions, not Summit allowances, vehicle dimensions or a claim that this load fits any model above. Photos can help explain irregular shapes, but measurements and the seating plan still need confirmation. Adding up bag volume alone does not show whether the items fit through the opening or pack together.

Children, strollers and mobility equipment

Include children in the passenger count. Share each child's age and the information needed to select a suitable restraint, such as height and weight, then ask Summit to confirm the appropriate seat, availability, installation arrangement and any charge. A child seat uses a passenger position and may affect adjacent space or access; it does not create an additional place.

For a stroller, say whether it folds in one piece or separates into a frame and carrycot. Measure each part that must travel. The stroller occupies luggage space in addition to your cases.

For a wheelchair or other mobility aid, provide its folded dimensions and explain the assistance needed for boarding. Confirm vehicle suitability with the team; a large vehicle should not be assumed to have a ramp or adapted access.

Three requests that need different checks

Two adults with two large cases and two cabin bags: start by asking whether the BMW 735i can accommodate the measured load. Passenger count alone does not confirm it.
Four adults, two children, four cases and a stroller: shortlist the Escalade ESV and V300, then compare the confirmed child-seat positions, access and luggage arrangement.
Seven adults with six large cases and cabin bags: the V300's headline counts are not enough to confirm the booking. Ask whether the allocated vehicle can take everything or whether a different arrangement or additional vehicle is needed.

These are enquiry examples, not approved loading plans.

Your booking checklist

Send the number of adults and children, all bag counts and dimensions, folded equipment measurements, child-seat needs, pickup details and any access concerns. Ask for written confirmation of the allocated vehicle or category and its suitability for that complete combination.

For airport travel, review the airport transfer service and pickup coordination guide. For several stops, compare hourly chauffeur packages. Request a vehicle recommendation with the full passenger and luggage list before choosing by model name alone.
