The towing limit is exceeded by 50 kg!
It is not allowed to drive with this Polar. 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 2.2 Direkt [6MT] with a Polar 590 with an actual weight of 1550 kg is a match just suitable for most journeys but also with some limitations.
The motor preformance of the Opel is in general more than sufficient. But the weight of the Polar with a normally distributed User Payload (200 kg in the caravan and 200 kg in the car including passengers), is (too) heavy. Move the luggage from the caravan to the car and drive not too fast and carefully. Remember to load your caravan correctly, insuring that the noseweight of the caravan is sufficient and the weight is distributed properly. But even so, a starting caravan driver is better off choosing a smaller and less heavy caravan!

Opel Vectra 2.2 Direkt [6MT] Polar 590
Actual Weights
Polar 590: 1550 kg.
Opel Vectra 2.2 Direkt [6MT]: 1660 kg.
Noseweight: 85 kg.
Actual weight ratio: 93%.
Performance
The engine's performance is generally fairly good on flat roads (performance score to compare 198 points).
Speeds of 68 mph (110 km/h) to 74 mph (120 km/h) are often quite possible.
There is only moderate power at low engine speeds (score to compare 117 points).
Slightly higher revs (2700 rpm) may be necessary under normal conditions on flat roads.
Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 20.8 sec.
In the mountains the performance is generally good (score to compare 207 points).
No problems are to be expected on steep mountain roads. Hill starts are possible on steep slopes up to 13%, but do require some experience from the driver.
On motorway inclines higher revs (4300 rpm) are needed.
A speed of 60 mph (97 km/h) is usually possible on most motorway inclines.
Weight
The towing limit is exceeded by 50 kg (check this in your vehicle documents).
If you passed your driving test after 1 January 1997, you will need a B+E (or B96) driving license.
Weight ratio between the laden caravan and the loaded car is 93%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 106%.
The risk of snaking at higher speeds, strong side winds and thoughtless driving is great. 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 a lot of knowledge and experience in driving a caravan it should be safe to drive slowly. Proper and careful loading is essential! An electronic stability system in the car and / or on the caravan is definitely recommended.
Recommended noseweight is 85 kg.
Safe speed up to 50 mph (80 km/h).
Stability and safety score to compare is 80 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.
Proper and careful loading is essential!
It's a fairly good match, only for experienced (caravan) drivers and with some limitations.
Influence of User Payload on stability
Weight distribution and noseweight are vital in obtaining a stable caravan.
