The Saab 9-3 sport sedan 1.9 TiD 8v with a Lunar Zenith 5 with an actual weight of 1205 kg is in general a good match and suitable for all journeys on all kinds of roads.
The motor preformance of the Saab is in general fairly good. And also 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 very good.

Saab 9-3 sport sedan 1.9 TiD 8v Lunar Zenith 5
Actual Weights
Lunar Zenith 5: 1205 kg.
Saab 9-3 sport sedan 1.9 TiD 8v: 1765 kg.
Noseweight: 70 kg.
Actual weight ratio: 68%.
Performance
The engine's performance is generally good on flat roads (performance score to compare 206 points).
Speeds of 71 mph (114 km/h) to 77 mph (124 km/h) are often quite possible.
There is sufficient power at low engine speeds (score to compare 180 points).
Slightly higher revs (1800 rpm) may be necessary under normal conditions on flat roads.
Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 21.6 sec.
In the mountains the performance is generally good (score to compare 218 points).
No problems are to be expected on steep mountain roads. Hill starts are possible on steep slopes up to 15%, but do require some experience from the driver.
On motorway inclines higher revs (2900 rpm) are needed.
A speed of 61 mph (98 km/h) is usually possible on most motorway inclines.
Weight
The towing limit of the Saab 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 68%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is INF%.
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 192 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.
