Another update: I tightened some hoses in the cooling system, re-filled the coolant, bled the system and the cooling system is back in running order with no signs of a leak anymore. Something must've gotten loose over the winter storage months which resulted in that minor coolant leak. Everything looks tight once again.
The car is still for sale however this snow/weather isn't really helping. I did get the car out of the garage for a quick spin and it feels fantastic! Even though the top was up, I had a huge smile on my face just zipping it around the neighborhood. Unfortunately, I have so little time to drive this car that I am still interested in selling it. I took some more photos which I will upload and post here once I'm back in town.
