The BMW 525i aut. with a Bailey Ranger 500/5 with an actual weight of 1244 kg is in general a good match and suitable for all journeys on all kinds of roads.
The motor preformance of the BMW is in general fairly good. And also the weight of the Bailey with a normally distributed User Payload (200 kg in the caravan and 200 kg in the car including passengers), is very good.

BMW 525i aut. Bailey Ranger 500/5
Actual Weights
Bailey Ranger 500/5: 1244 kg.
BMW 525i aut.: 1805 kg.
Noseweight: 70 kg.
Actual weight ratio: 69%.
Performance
The engine's performance is generally good on flat roads (performance score to compare 242 points).
Speeds of 76 mph (123 km/h) to 81 mph (131 km/h) are often quite possible.
There is sufficient power at low engine speeds (score to compare 190 points).
Slightly higher revs (2200 rpm) may be necessary under normal conditions on flat roads.
Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 16.1 sec.
In the mountains the performance is generally very good (score to compare 292 points).
No problems are to be expected on steep mountain roads. Hill starts are possible on steep slopes up to 19%.
On motorway inclines higher revs (3500 rpm) are needed.
A speed of 68 mph (110 km/h) is usually possible on most motorway inclines.
Weight
The towing limit of the BMW is more than sufficient (check this in your vehicle documents).
If you passed your driving test after 1 January 1997, a B driving license is enough.
Weight ratio between the laden caravan and the loaded car is 69%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 78%.
The chance of snaking is relatively small at normal speed, if the caravan is well loaded.
Recommended noseweight is 70 kg.
Safe speed up to 62 mph (100 km/h).
Stability and safety score to compare is 184 points.
If the caravan starts to snake you should reduce your speed and slow down directly! Lift your feet off the accelerator and brake gradually. Hold the steering wheel into a fixed position.
Conclusion
Performance is fairly good.
Safe driving is possible.
It's a perfect match!
Influence of User Payload on stability
Weight distribution and noseweight are vital in obtaining a stable caravan.
