Recently towed a double axle car transporter, with a car on the back, approximately 30 miles. Car was a mk2 fiesta, not sure about weight, and have also had an mx-5 mk1 on the back. My diesel coped 100% in regards to the comfort, not too much bouncing about etc.
Power wise it managed mine, but then again mine has been mapped to give a bit of extra grunt, so mite be a tad unfair to say you can tow it with ease..
Tho before had towed a Jet-ski on the back with no problems at all, rather larger 3 seater Seadoo.
Hope this helps.
