The towing limit is exceeded by 137 kg!
It is not allowed to drive with this Lunar. Make sure the towing limit is correct.
We now give advice based on the assumption that the legal maximum towing weight is higher for your car and that the car should be allowed to tow this caravan!
The Opel Vectra 2.0 Dti with a Lunar Lexon SE with an actual weight of 1437 kg is in general a good match and suitable for journeys on most kinds of roads, sometimes with some limitations in the mountains.
The motor preformance of the Opel is in general sufficient. But the weight of the Lunar with a normally distributed User Payload (200 kg in the caravan and 200 kg in the car including passengers), is quite heavy. Proper and careful loading is essential and don't drive too fast. Remember to load your caravan correctly, insuring that the noseweight of the caravan is sufficient and the weight is distributed properly!

Lunar Lexon SE: 1437 kg.
Opel Vectra 2.0 Dti: 1665 kg.
Noseweight: 80 kg.
Actual weight ratio: 86%.
Performance
The engine's performance is generally fairly good on flat roads (performance score to compare 175 points).
Speeds of 66 mph (106 km/h) to 72 mph (116 km/h) are often quite possible.
There is only moderate power at low engine speeds (score to compare 114 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 26.1 sec.
In the mountains the performance is generally fairly good (score to compare 163 points).
No problems are to be expected on steep mountain roads. Hill starts are possible on steep slopes up to 12%, but do require some experience from the driver.
On motorway inclines the speed drops despite high revs.
A speed of 55 mph (89 km/h) is usually possible on most motorway inclines.
Weight
The towing limit is exceeded by 137 kg (check this in your vehicle documents).
The car is too heavily loaded.
Weight ratio between the laden caravan and the loaded car is 86%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 98%.
The risk of snaking at higher speeds, strong side winds and thoughtless driving exist. Even if the combination normally feels stable, the forces by deflection side to side are so great that it could be dangerous. Only if the driver has knowledge of and experience in driving a caravan it should be safe to drive. Proper and careful loading is essential! An electronic stability system in the car and / or on the caravan is recommended.
Recommended noseweight is 80 kg.
Safe speed up to 56 mph (90 km/h).
Stability and safety score to compare is 116 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 sufficient.
Proper and careful loading is still important!
It's a good match, sometimes with some limitations in the mountains.
Influence of User Payload on stability
Weight distribution and noseweight are vital in obtaining a stable caravan.
