Is the Auto-Sleepers M Star a suitable luxury campervan?
The Auto-Sleepers M Star is a premium two-berth campervan built on the extra-long wheelbase Mercedes-Benz Sprinter. It is designed for couples seeking the interior volume of a coachbuilt motorhome within a van conversion profile. With a 190bhp engine, automatic transmission, and Grade 3 insulation, it provides a high-specification environment for four-season touring, though its significant length and 4100kg weight require specific driving considerations.
- Extra-long wheelbase Mercedes-Benz Sprinter chassis with 190bhp engine.
- Rear lounge layout converting to twin beds or a large double.
- High-specification kitchen featuring authentic Corian work surfaces.
- MBUX 10.25-inch touchscreen with 3D Navigation and 9G-Tronic transmission.
- Grade 3 thermal insulation for year-round touring capability.
Worth knowing: The 7.37 metre length requires careful navigation in urban environments. A 4100kg MTPLM means drivers must hold the appropriate C1 licence category. Payload management is necessary when adding factory optional equipment.

| Model | Berths | Maximum weight | Length | Typical price |
|---|---|---|---|---|
| Auto-Sleepers M Star | 2 | 4100 kg | 7.37 m | £115,000 to £140,000 |

The Auto-Sleepers M Star occupies a distinct position in the market, utilizing the extra-long Mercedes-Benz chassis to provide more internal volume than standard 6.36 metre conversions. While it offers superior engine power and high-end finishes like Corian surfaces, it requires a larger financial investment and a C1 licence compared to the brand's 3500kg alternatives. The choice between this and smaller models depends on whether the buyer prioritises interior lounge space over urban manoeuvrability.
Worth knowing: Specifications and prices can vary by model year, trim and optional equipment.
Ownership considerations for the M Star
- Utilise the 3D Navigation and driver assistance systems to manage the vehicle's dimensions.
- Make use of the Grade 3 insulation for off-season touring to maximise vehicle utility.
- Regularly check the electronic parking brake and MBUX software updates.
Common mistakes to avoid
- Underestimating the turning circle required for the extra-long wheelbase chassis.
- Exceeding the 605kg payload by not accounting for heavy optional extras.
Worth knowing: The 7.37 metre length exceeds standard UK parking bays.
