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.

Car sometimes won't start randomly?

I have a ford ka, that randomly doesn't start there isn't any pattern with it. When it starts is perfectly fine, its 11years old.

It sometimes sounds like its going to start but then doesn't, always fire. I cycle the key a few times and it will eventually go. If I start it every few hours its fine, bit if I leave it it doesn't want to start.

Its had the spark plugs changed and some other sensors as well as the leads to the engine (I'm not sure the correct names) the car it self sounds better but it still sometimes doesn't want to start.

Any ideas why or is it just getting to the end of its life?

What do I need for a Sony car stereo in a ford KA 2004?

Ok so I'm currently in Australia and I'm looking at buying a Sony stereo to take back to England with me for my Ford KA. I know that I already need to buy a new fascia, wire harness and aerial adapters but some people are saying I need another wire harness specially for Sony. Is this true if so will it come with the harness or do I need to buy it separately?

Car randomly won't start sometimes?

I have a ford ka that's 11years old runs perfectly when started.

At the minute it randomly doesn't want to start sometimes I manage to be it started by pressing the accelerator and only once has it refused completely. It starts but doesn't always fire straight away there's no pattern at all with it, the weather makes no odds.

But it always seem to be first thing if its not going to start it will be first time, and then its fine for the rest of the day.

Its had the spark plugs changes and leads changes from the engine (I don't know the correct name for them) and ot gets a bottle of redex every few months put through.

Apart from not wanting to start sometimes the car is fine, any ideas?
