Suggestions for a small car with some towing capacity?

I'm looking for some suggestions for a small, fuel efficient, car that has some towing ability. I'm not the most confident driver hence why i'm looking for something small, but I also need to be able to tow a trailer carrying my sons dirtbike. The bike only weighs 80KG so it wouldn't be a very heavy load.
I've also seen various setups that allow a bike to be moved via a hitch mount which looks more ideal than using a trailer, but these have all been on larger cars.
Cars looked at so far:
Ford KA: Not allowed to Tow ANYTHING
Fiat 500: Not allowed to Tow ANYTHING (According to what i've read)
Toyota Yaris: Seems a little big:/
Can anyone offer any more suggestions?
Would be much appreciated.

Thanks. Yaris is a little big?

Seriously, to tow ANYTHING you need a vehicle with at least some weight and power. I would suggest something like a Corolla as a minimum.

And brush up on your driving skills, even with a light trailer you need a bit more care when driving and the car performs sightly differently.

Now you CAN tow a small trailer behind a compact car, but you want something 1600cc or bigger.

Toyota Matrix / Corolla is one of the picks. So, you are such an unconfident driver you need a car as small as Fiat 500, BUT you are confident to tow a trailer? I suggest building up your confidence in a reasonable size family car. There are lots to choose from. How about a Ford Focus? If you believe the Toyota Yaris "seems a little big" you will not find a vehicle with towing capability in your desired size. You need to limit your search to vehicles which have at least a 1.8L engine. 2.0L or 2.3 would be even better. Get a small pick up or SUV. If you are only using it for this find a used one. I would not really worry about gas because it will be used little. Those vehicles tend to last a long time.
