The Bailey Unicorn Madrid S4 is a single axle caravan featuring a 3 to 4 berth layout, built using Alu-Tech timberless construction. It is distinguished by a side dinette that converts to bunk beds and a full-width rear washroom. With a 7.11m length and a 1496kg MTPLM, it includes high-specification features such as Alde central heating and a vertical front infinity window. Used prices typically range between 17500 and 24000.
Worth knowing: The 1496kg MTPLM requires a tow car with sufficient power compared to entry-level caravans. Bunk bed dimensions may be restrictive for taller teenagers. Front locker storage capacity is reduced compared to previous Unicorn generations.
Worth knowing: Payload is limited to 155kg, requiring careful management of heavy equipment. The vertical front window provides significant light but may affect privacy in certain pitches.
| Model | Berths | MTPLM | Length | Typical price |
|---|---|---|---|---|
| Bailey Unicorn Madrid S4 | 4 | 1496 kg | 7.11 m | £17,500 to £24,000 |
| Bailey Unicorn Deluxe Vigo | 4 | 1500 kg | 7.34 m | £18,500 to £33,995 |
| Bailey Unicorn Deluxe Cadiz | 4 | 1500 kg | 7.34 m | £17,500 to £33,500 |
The Bailey Unicorn Madrid S4 occupies a specific niche in the Unicorn range, offering a 7.11m length that is shorter than the 7.34m Unicorn Deluxe Cadiz or the 7.37m Cabrera. While it shares the 1496kg MTPLM of the Unicorn Deluxe Madrid, it provides a different balance of internal space and towing weight. It remains a competitive choice for those prioritising a side dinette over fixed bedding, though buyers must weigh the 155kg payload against their touring requirements.
Worth knowing: Specifications and prices can vary by model year, trim and optional equipment.
Worth knowing: Ensure the 155kg payload is not exceeded when fitting optional extras like motor movers.
