My personal non-professional feeling is a 16 foot trailer might a little big for your station wagon to tow for very long distances. I think a lot depends on how far you want to tow. If you're only going down to the river, or to a show, and you're going less than 25 miles, in the daytime, in nice weather, you won't have to worry as much as you would if you were going hundreds of miles.
I'll tow my Hillbilly RV 1,600 miles, day/night/rain/shine and then two weeks later turn around and tow it back 1,600 miles.

If you intend to tow very much, you should go to a place that installs hitches and let them do the work. Believe me, the last thing you want is for your hitch to fail while you're running along about 60 mph.
