that "blue ox" thing must be for drag strip cars or something.
A normal street car would not have those prongs sticking out of the grill........
When any vehicle is setup for 4-wheel-down towing, it will have two protrusions of one kind or another. They are removable with a turn & pull out feature leaving behind the holes in the grille. I would assume the pair of pins pictured on the yellow Solstice works the same way but were not removed when taking the picture for the sake of education.
I tow my Jeep Liberty with all wheels on the pavement, all the time with a motorhome. Years ago I towed a 2000 MR2 Spyder the same way.
You buy a specific structure made for the vehicle called a tow bar bracket. It resembles a rear hitch without the receiver, instead with two mounting points for a tow bar. Those two pins are attached to the bracket behind the bumper cover.
Here are some pictures of my two tow vehicles, past and present being towed. I cannot do the same with the Solstice I am buying because it is an automatic and also because it is a GXP. Apparently the tow bar bracket can't be mounted on a GXP because the turbo introduces a unique interference.
This picture was taken before I added a riser to level the tow bar to eliminate "bucking"
The riser attached to the motorhome is required for the Liberty, but was not required to tow the MR2.
I decided I will be driving the Solstice home. I am forgetting about towing it. Between the automatic transmission and low ground clearance, it's not worth the risk. Add the cost to rent a tow dolly ($265) or a trailer ($530) adds salt to the wound.
Thanks for your comments and input.
