There are a few factors that will complicate things...
First, what size is your engine? a V8 will obviously have more towing power than a straight six.
Is the car a manual or automatic? A manual is more versatile and lets you use the whole range of engine power, an auto may require a transmission cooler for heavy duty towing.
What are you towing? The tongue weight of a trailer is a big factor when towing with a car.
What condition is your car in? A forty year old car with an original engine probably couldn't pull a drunken sailor off a dead hooker.
The straight answer: if your car runs well, a reasonably in shape adult male can lift the tonge of your trailer and your car has a manual transmission and a straight six engine then you can pull about 2000 kg max, a little more with a V8. a little less with an auto transmission. The best way is to test it out, tow the trailer around for a while, if you really struggle up hills then it is best not to do long distance, trailering is tough on a car and will be double tough on a car that old, make sure your brakes are in good working order!!! - hope this helps, good luck!
