The Opel Vectra 1.9 CDTi with a Lunar Quasar 546 with an actual weight of 1395 kg is in general a good match and suitable for all journeys on all kinds of roads.
The motor preformance of the Opel is in general more than sufficient. And also the weight of the Lunar with a User Payload (165 kg in the caravan and 200 kg in the car including passengers), is not too heavy, if the caravan is well loaded.

Noseweight: 75 kg.

Performance
The engine's performance is generally fairly good on flat roads (performance score to compare 198 points).
Speeds of 69 mph (112 km/h) to 76 mph (122 km/h) are often quite possible.
There is sufficient power at low engine speeds (score to compare 158 points).
Slightly higher revs (1900 rpm) may be necessary under normal conditions on flat roads.
Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 22.8 sec.
In the mountains the performance is generally fairly good (score to compare 199 points).
No problems are to be expected on steep mountain roads. Hill starts are possible on steep slopes up to 14%, but do require some experience from the driver.
On motorway inclines the speed drops despite high revs.
A speed of 59 mph (95 km/h) is usually possible on most motorway inclines.
Weight
The towing limit of the Opel is 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 77%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 86%.
There is a small chance of snaking at higher speeds, strong side winds and thoughtless driving. Even if the combination normally feels stable, the forces by deflection side to side are great at high speed. For drivers with knowledge of, and experience in driving a caravan it is safe to drive, but proper and careful loading is still important! An electronic stability system in the car and / or on the caravan is worth considering.
Recommended noseweight is 75 kg.
Safe speed up to 56 mph (90 km/h).
Stability and safety score to compare is 147 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 more than sufficient.
If the caravan is well loaded 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.
