Hello Steve,
Our first tow car was a 5 door 2.0D Peugeot 307 and it was very good, economical and with enough power for our needs at the time. However, on rare occasions it sometimes felt as if the "tail was wagging the dog" and we soon bought a car with a better towing capacity.
It's a fair few years since we moved on to bigger vans and cars, but from memory the kerbweight of the 307 was around 1300kg, which just about covers your requirements. To be on the safe side I would check the kerbweight of your model and think hard on your caravan's max weight when it's in full holiday guise.
