I have not purchased a Smart Car as of yet.

I am looking for a more economical way to get my Wave Runner to the locations near me, instead of using my Avalanche.

I am researching the different models.
Does anyone know the actual towing capacities on the different versions, new or used?
So far by my calculations here is where I am at:
SmartCar Towing Capacity: ?
SmartCar Hitch Capacity: 1000 lbs (100 lbs max adds to GVW)
Wave Runner WET: 924 lbs (assuming 8 lbs per gallon of gas, 18 gallons)
Trailer Wieght: ? (I can lift it myself not too heavy - 76 lbs left)
Any insight into the Tow Capacities would be awesome.
I prefer the convertible.
