Just checking before I start sweet talking for a lorry.... A 1.6 ford escort couldn't pull the lightest wieght of trailers with a 16.1hh (prospect of 16.3hh
not sure how helpful this is but I have a 2.0 litre engine car and I thought it would tow ok. I looked up the towing weight in the car manual and it wasn't! So I wouldn't think yours would either...
If it helps, my Nissan Primera 2 litre TD is fine with the baby Bateson trailer - 675k and my 14.2 cob - 390k. I won't tow with anything other than something of his size and only one small horse even though the trailer is designed for two 14.2s or a mare and foal without the partition.
I have 235k in reserve for my towing capacity.
I think a 1.6 engine will be too small and the weight of your car not enough.
