Car for Bailey Discovery D4-4

Hi Folks,

My wife and I are considering purchasing a Bailey Discovery D4-4 was looking for some advice as completely new to touring.
My car is a 2013 Astra 1.6 Sri,  The power and weight specs are
Power   113 bhp | Weight  1578kg | Torque  155 Nm, 114 ft-lb

The Bailey Discovery D4-4 specs are
Shipping Length - 7.141m / 23′5″
Internal Length - 5.398m / 17′9″
Overall Width - 2.228m / 7′4″
MTPLM - 1206kg
MRO - 1059kg
Payload - 147kg 

I know as much as I won't be able to tow much due to the restriction on my licence 3500kg combined weight.
I just want to seek advice about my cars ability to tow this caravan. Weight wise it should be ok, but because it is a SRi with a low profile, bhp of 113 and Torque of 114 ft-lb I’m unsure if it has enough power to tow this caravan.
I would really appreciate any advice on the above.

Thank you,
Blaine
