I tow a 1500kg boat with my 175kw VZ ute. The factory clutch isnt really the best, but does the job.
Just becuase you dont have a boat ramp to contend with, you still have hill starts at traffic lights etc to worry about.
A few trips a year wont wear out the clutch. Just try and reduce the number of hill starts you do and reduce any manourvering you need to do. Especially on a incline.
Make sure you have the right tow pack. You need at least the 1600kg tow pack to tow another car. A dual axle car trailer is normally 500odd KG on its own. The 2000odd KG tow bar would be best.
