With the help of a couple handy friends we designed a class 1 hitch for my Roadster.

I purchased a small trailer frame from Northern Tool & Equipment

I attached two additional cross rails to accommodate the fastening of a car top carrier using the supplied hardware used to attach it to a roof rack.

The hitch consists of a flat piece of steel 3"x1/4 thick bolted to the centre frame cross-member and runs directly in line under the muffler. (Two opposing bends were necessary to provide clearance under the muffler)
We welded the receiver (square tubing) to the underside of the flat steel with an extra collar heated and pressed over it to prevent any possible deforming at the edges.

Then we positioned and welded two 1"X 1/4 thick pieces of flat steel in a "V" angle that hides partly behind the muffler tips and extends to the back side of the trunk. We drilled two holes in each support and sandwiched them between the trunk and plate steel on the inner trunk surface.

The longitudinal plate steel handles any push pull of the loaded trailer (Max 500lbs)
The V cross- members stabilize any side to side movement or sway.

The hitch outlet hardly noticeable standing at the rear of the vehicle

The whole trailer with luggage carrier weighs under 200lbs.

The hitch also accommodates my bike rack.

The carrier is removable from the trailer (4-bolts) for multi-purpose use. I have a class two hitch on my Altima so I can utilize the trailer for odd jobs.

We are traveling to the Oregon coast for our 25th anniversary, luggage in tow.

Cheers!
