Go to a U-Haul joint or a Pep Boys. They specialize in installing trailer hitches on about anything. It’ll probably only be a class 1 or 2 hitch, but on a car for just pulling a boat around, bfd.
Just for reference, I had a trailer hitch installed on my 1998 Taurus GL in 2001 to be able to pull a 14′ SmokerCraft with a 35HP motor on it. Sadly, I never could find a motor I could afford at the time, so I ended up selling the boat. BUT, the hitch worked perfectly and they were able to put it on a Taurus, which is too low to the ground to get under without jacking and has a unibody to boot.
They can get a hitch on your Tiburon, trust me.
